Invention field
The present invention relates to have with ad hoc fashion stimulates or platelet increasing generates or strengthen the active new protein of megalokaryocyte progenitor cell hyperplasia and differentiation, the said protein DNA sequence of encoding and preparation method thereof in vivo.
Background of invention
Megalokaryocyte is the syncyte that cell space is big, be rich in endochylema, and it can produce thrombocyte, is mainly seen in the marrow.Megalokaryocyte originates from the pluripotential hemopoietic stem cell in the marrow.The primary multipotential stem cell is divided into the megalokaryocyte progenitor cell in certain program, the latter is fixed to megakaryocytic series.Megalokaryocyte progenitor cell hyperplasia and be divided into megakaryoblast.Megalokaryocyte further carries out polyploid and tenuigenin maturation, at last its seedless kytoplasm fragment (being thrombocyte) is discharged in the circulation.A sophisticated megalokaryocyte on average forms 2,000-4,000 thrombocyte.Although hematoblastic formation mechanism it be unclear that on some details, but it is believed that, megalokaryocyte is positioned at albumin (albuminal) surface of bone marrow sious chamber endothelium typically, and its produces prolongs and the endochylema treating processes of sinusoid, takes this megalokaryocyte and carries out hematoblastic fragmentation.
Also there are many doubtful points in the hematoblastic mechanism of relevant generation, although think and might be present in marrow venous sinus cortex by megalokaryocyte, kytoplasm passes cortex, produces rope sample projection on the vein inwall, takes this, and thrombocyte is released.
It is believed that, have a kind of specific function in generation that produces for megalokaryocyte hematopoiesis thrombocyte and the regulation and control.In healthy human and animal, though known to after for example healthy animal is used antiplatelet antibody, platelet count reduces rapidly, begins then to rise to temporarily to be higher than usually, returns back to normal level at last, so effective hematoblastic quantity is maintained at certain level.Equally, known in clinical platelet count reduce (thrombocytopenia) or platelet count and increase (thrombocytosis) even see red corpuscle and blood cell count when being in normal level.
Carry one in passing, the thrombocyte most important function is to form thrombus in hemostatic mechanism.If hemostatic mechanism then will cause bleeding tendency because platelet count reduces and can not normally play a role.
Proved that there are specific regulation mechanism in relevant megalokaryocyte generation and thrombocyte in generating.Thrombocyte is being kept effectively quantity in healthy human body and in the normal animal.Yet known when antiplatelet antibody is applied to animal, platelet count only reduces rapidly in a short time, and bottom out afterwards and the temporary transient normal level that surpasses finally return back to normal level.In clinical field, also recognize, platelet count reduce (thrombocytopenia) or platelet count increase (thrombocytosis) in addition see red corpuscle and the normal situation of leukocyte count under.But, still do not have the report that successfully separates and identify the particular adjustments factor that relates to thrombocyte and produce (for example, resemble in the red corpuscle forming process erythropoietin) so far.
The thrombocyte most important function is to form blood clot in hemostatic mechanism.When the normal function of hemostatic mechanism goes to pot because of thrombopenia, then bleeding tendency can take place.In the radiation and chemotherapy field of cancer, being reduced by the state's platelet due to the bone marrow depression is lethal complication; Give this class patient platelet transfusion to prevent bleeding tendency.The thrombocyte infusion also is applied to the patient after the bone marrow transplantation or the patient of aplastic anemia.
The thrombocyte that is used for this class thrombocyte infusion can be prepared by the blood of healthy blood donor by the thrombocyte method of removing, but it is short to be used for hematoblastic transformation period of this class of infusion, and might produce bacterial contamination.Having polluted lymphocyte in the thrombocyte that the thrombocyte infusion also may be used because of infusion exists and makes the patient contact harmful virus (as human immunodeficiency virus HIV or various hepatitis virus), induces major histocompatibility antigen (HLA) to platelet transfusion that specific antibody is arranged or cause the danger of graft versus host disease (GVHD).
Therefore, if can form at thrombocytopenic patient's body internal stimulus inherent thrombocyte, and reduce the dependency of thrombocyte infusion simultaneously, this will be very useful.In addition,, just can make this class treatment safer, might increase the intensity of treatment and further improve desired anticancer effect if can correct or prevent to carry out the cancer patients's of radiotherapy or chemotherapy thrombopenia.
For all the foregoing reasons, people are to separating and identifying to relate to and regulate megalokaryocyte and thrombopoietic specificity regulatory factor has carried out a large amount of research.According to results of in vitro studies, the regulatory factor that the control megalokaryocyte generates roughly is divided into following two kinds of factors (referring to Williams etal., J.Cell.Physiol., vol.110, p 101-104,1982).Megakaryocyte colony stimulating factor (Meg-CSF) is in semisolid medium moderate stimulation CFU-MK hyperplasia and breaks up to form the regulatory factor of megakaryocyte colony.The regulatory factor that another kind is called megalokaryocyte synergistic factor (Meg-Pot), megakaryocyte stimulating factor, thrombopoietic-stimulating factor etc. mainly acts on prematurity or sophisticated megalokaryocyte, takes this to strengthen its differentiation with ripe.In some cases, Meg-Pot can be detected with Meg-CSF.In addition, because platelet count increases in the time will being applied to other intact animal by serum of testing the collection of inductive thrombopenia animal or blood plasma, so show to exist a kind ofly can promote the thrombopoietic promotion factor in vivo, be called thrombopoietin (TPO).
In recent years, checked that the cytokine stimulating megakaryocyte that some its genes have been cloned generates and thrombopoietic ability.People IL-3 stimulates the formation (Bruno etal., Exp.Hamatol., vol.16, p371-377,1988) of people's megakaryocyte colony, and the platelet count of the monkey that raises at least (Donahue et al., Science, vol.241, p1820,1988).Yet,, generate and thrombopoietic specificity regulatory factor so it is different from the control megalokaryocyte because IL-3 works to the hyperplasia and the differentiation of all hematopoietic cells.People IL-6 does not show the Meg-CSF activity, but it acts on immature megalokaryocyte, and promotes it to be divided into sophisticated megalokaryocyte (Williams et al., Exp.Hamatol., vol.18, p.69,1990).Use IL-6 in the body and can induced platelet generate, promote the ripe of Primates bone marrow megakaryocyte and be transferred and promoted, but also produce some side effects to Hyperploidy more, as lose weight, induce acute phase protein (Asano et al., Blood, vol.75, p1602-1605,1990; Stahl et al., Blood, vol.78, p1467-1475,1991).People IL-11 does not have the Meg-CSF activity, but the Meg-Pot activity is arranged, and promotes the thrombocyte of mouse to generate (Neben et al., Blood, vol.81, p901-908,1993).In addition, people LIF improves platelet count (Mayer et al., Blood, the vol.81 of Primates significantly, p3226-3233,1993), but its external to Megakaryocytic effect very faint (Burstein et al., J.Cell.Physiol., vol.153, p305-312,1992).
Although hope is applied to these cytokines as the thrombocyte synergistic factor clinical, its function is not special to megakaryocytic series, and they can cause side effect.Therefore, need clinically to develop and a kind ofly not only megalokaryocyte-platelet system had been had specificity but also can cause that the thrombocyte of less side effect increases the factor.
Meg-CSF, Meg-Pot or TPO activity have been found in serum, blood plasma or the urine of thrombocytopenic patient or animal or in some human cell line's who is cultivated culture supernatants, to exist.Yet, still do not know that whether these activity cause because of the common existence that has single kind factor or several factors, do not know whether these factors are different with known cytokine yet at present.
People such as Hoffman find that aplastic anemia and no megalokaryocyte thrombopenic purpura patient's serum contains the Meg-CSF activity, and it increases formation (the Hoffman et al. of megakaryocyte colony significantly, N.Eng.J.Med., vol.305, p533-538,1981).After this, people such as Mazur report that again the Meg-CSF activity that is present in the Patients with Aplastic Anemia serum is different from IL-3 and GM-CSF (Mazur et al., Blood, vol.76, p290-297,1990).Similarly the Meg-CSF activity has seen (Mazur et al., Exp.Hematol., vol.12, p624-628,1984 in the cancer patients that accepts cytotoxicity chemotherapy widely and bone marrow transplantation patient's the serum; De Alarcon and Schinieder, Prog.Clin.Bio.Res., vol.215, p335-340,1986).According to people such as Hoffman, by purifying in low megalokaryocyte thrombopenia patient's the serum Meg-CSF, its apparent molecular weight is 46,000 (Hoffman et al., J.Clin.Invest., vol.75, p1174-1182,1985), but discover that further said material is not to have (Hoffman Blood with the purity level that can carry out accurate amino acid sequencing, vol.74, p1196-1212,1989).From thrombopenia patient's blood plasma or idiopathic thrombocytopenic purpura (ITP) patient's urine partial purification have the active material of TPO sample, it can strengthen 75The Se-Sethotope mixes in the new thrombocyte that forms of mouse, and the apparent molecular weight of the blood plasma source factor of being measured is 40,000 (Grossi et al., Hematologica, vol.72, p291-295,1987; Vannucchi et al., Leukemia, vol.2, p236-240,1988).
Meg-CSF activity and TPO sample activity also detect (Kawakita et al., Br.J.Haemtol., vol.48, p609-615,1981 in aplastic anemia and severe ITP patient's urine sample; Kawakita et al., Blood, vol.556-560,1983).People such as Kawakita further report, urinate Meg-CSF activity seen in the extract the aplastic anemia patient, show that through gel-filtration its apparent molecular weight is 45 under the disassociation condition, 000 (vol 62 for Kawakita et al., Br.J.Haematol., p715-722,1986).People such as Erikson-Miller have also reported purifying Meg-CSF from similar urine sample, but do not provide information (the Erikson-Miller et al. of relevant its structure, " Blook Cell Growth Factors:their Present and future use inhematology and oncology " ed.by Murphy, AlphaMed Press, Dayton, Ohio, p204-220,1992).People such as Turner from bone marrow transplantation patient's urine purifying the active megakaryocyte stimulating factor of tool Meg-CSF (MSF) and clone its gene (Turner et al., Blood, vol.78, p1106-279a, 1991, (abstr., supple.1)).The molecular weight of this MSF is 28,000-35,000.This factor with so far in thrombopenia patient's serum and plasma sample the consistence of detected Meg-CSF and thrombocyte thereof increase activity and still await illustrating.
People also from the culture supernatants of the clone (HEK cell) in human embryo kidney (HEK) source purifying tool TPO sample activity, molecular weight be 32,000 material, and its biology and biochemical characteristic done to detect widely, but its structure it be unclear that (McDonald et al., J.Lab.Clin.Med., vol.106, p162-174,1985; McDonald, Int.J.Cell Cloning, vol.7, p139-155,1989).On the contrary, according to other researchist, the main activity of the stripped enhancing megakaryocytic maturation process that in the conditioned medium of HEK cell, produces, be because known cytokine, be (Withy et al., J.Cell.Physiol., the vol.15 that IL-6 and EPO cause, p362-372,1992).
People such as Evatt have reported the factor of relevant animal-origin, and they are finding and can promote in rabbit in antiplatelet sera injection institute inductive thrombopenia rabbit plasma 75The Se-Sethotope mixes the TPO sample activity (Evatt et al., J.Lab.Clin.Med., vol.83, p364-371,1974) in the thrombocyte of new formation.In addition, a large amount of similar results of study (for example, Odell et al., Proc.Soc.Biol.Med., vol.108, P428-431,1961 from the sixties to the seventies, have been reported; Evatt and Levin, J.Clin.Invest., vol.48, p1615-1626,1969; Harker, Am.J.Physiol., vol.218, p1376-1380,1970; Shreiner and Levin, J.Clin.Invest., vol.49, p1709-1713,1970; Penington, Br.Med.J.vol.1, p606-608,1970).People such as Evatt and Hill and Levin from the thrombopenia rabbit plasma partial purification TPO sample activity (Evatt et al., Blood, vol.54, p377-388,1979; Hill and Levin, Exp.Hematol., vol.14, p752-759,1986).After this, proceeded purifying work to this factor, monitor it and show that in external promotion megalokaryocyte differentiation and ripe active (being the Meg-Pot activity) when detecting with gel-filtration, this active apparent molecular weight is 40,000-46,000 (Keller et al., Exp.Hematol., vol.16, p262-267,1988; Hill et al., Exp.Hematol., vol.20, p354-360,1992).Since the IL-6 activity in the blood plasma that brings out severe acute thrombopenia rabbit through using antiplatelet sera, detect less than, thereby show that this TPO sample activity is a kind of factor (Hill et al., Blood, the vol.80 that results from outside the IL-6, p346-351,1992).
Tayrien and Rosenberg also from the culture supernatants of thrombopenia rabbit plasma and HEK cell purifying a kind of apparent molecular weight be 15,000 the factor, it can the Megakaryocytic clone of stimulation in rats produce platelet factor 4, but they did not provide information (the Tayrien and Rosenberg.J.Biol.Chem. of relevant its structure, vol.262, p3262-3268,1987).
In addition, Nakeff is finding Meg-CSF activity (Nakeff, " Experimental Hematology Today " ed.by Baum and Ledney in using the thrombopenia mice serum that antiplatelet sera brings out, Springer-Verlag, NY, p111-123,1977).On the other hand, thrombocytopenic rabbit anteserum can promote megakaryocytic maturation (keller et al., Exp.Hematol., vol.16, p262-267,1988; Hill et al., Exp.Hematol., vol.17, p903-907,1989), and the metamorphosis of stimulating megakaryocyte is thrombocyte (Leven and Yee, Blood, vol.69, p1046-1052,1989), but the Meg-CSF activity that can survey is not arranged.
Meg-CSF activity (Miura et al. has been provided in the thrombocytopenic rabbit plasma that is provided through inferior lethality integral radiation people such as Miura, Blood, vol.63, p1060-1066,1984), this explanation induces Meg-CSF active relevant with the megalokaryocyte minimizing in vivo, and irrelevant with thrombopenia, because do not change this activity (Miura et al. behind platelet transfusion, Exp.Hematol., vol.16, p139-144,1988).Mazur and South are detecting the Meg-CSF activity in inferior lethality radiating dog serum, and report that it is 175,000 (Mazur and South, Exp.Hematol., vol.13, p1164-1172,1985) that this factor records apparent molecular weight through gel-filtration.In addition, other researchist (as Straneva et al., Exp.Hematol., vol.15, p657-663,1987) has also reported the factor in serum, blood plasma and urine source.
Therefore, as mentioned above, found in the biological sample of taking from thrombopenia patient and animal that stimulating megakaryocyte generates and thrombopoietic condition activity, but because its content in natural origin (as blood and urine) is very little, so also fail to finish separation, biochemistry and biological assay and feature description to these factors.
Summary of the invention

Analysis is by the biological nature of thrombocytopenia rat plasma deutero-TPO
(1) measures in the system (liquid culture system) at rat CFU-MK
As typical example, Fig. 5 shown use from the partially purified TPO sample of thrombocytopenia rat plasma (by the purification step (8) of embodiment 1-2, describe, from the TPO active fraction F2 of YMCPack Protein-RP post) dose response curve.When microscopically is periodically observed cultured cells, identify Megakaryocytic generation with ripe, the increase of cell size just, this may carry out with the increase of megalokaryocyte number.Significant especially the variation is the formation of having found the megalokaryocyte projection the last day (almost can not identify the formation of Megakaryocytic projection in the time of the 3rd day) of just cultivating at the 4th day.Such projection forms and is called endochylema projection formation (Leven and Yee, Blood, vol.69, pp.1046-1052,1987) or the formation of thromboblast projection (Topp et al., Blood, vol.76, pp.912-924,1990), the latter is considered to the platelet precursors structure of further being broken up by ripe megalokaryocyte and is considered to be in the terminal stage of external present observable megalokaryocyte differentiation.Owing to observe so morphologic variation with the TPO sample with high frequency separately, possible this factor can stimulate CFU-MK propagation and differentiation alone, produces ripe megalokaryocyte and the final thrombocyte that discharges.
(2) in colony mensuration system
When adopting colony mensuration system to detect by the partially purified TPO sample of thrombocytopenia rat plasma, the TPO in rat plasma source has stimulated the formation of megakaryocyte colony, said colony the has been measured system applies cell or the Gp II b/III a of unsegregated rat bone marrow cell, each isolation/concentration step +The CFU-MK fraction.Compare with the megakaryocyte colony that causes by other cytokine such as rat IL-3, mouse GM-SF or people EPO, to be each colony be made up of the megalokaryocyte of peanut more the feature of the megakaryocyte colony that TPO causes, but each megalokaryocyte volume is bigger, this means ripen in advance.In addition, because TPO does not produce or only produce seldom other clone colony, the Meg-CSF of TPO is active thereby can be considered to megalokaryocyte specific.Based on these facts, clearly TPO has the biological characteristics that is different from other cytokine such as rat IL-3, mouse GM-CSF and people EPO, and unique Meg-CSF activity is arranged.
Partially purified TPO sample is also to CD34 in the blood plasma by the thrombocytopenia rat +, derive from the DR of human bone marrow cell or people's strand hemocyte +The cell fraction shows that its Meg-CSF is active and significantly increased the number of people's megakaryocyte colony, shows that this factor do not have species specificity.

Rat produces cell specific of TPO
(1) rat produces the screening of the organ of TPO
In order to guarantee to be used for the mRNA source of rat TPO gene clone, carried out screening that rat TPO produces organ and specific.At first, regularly, cultivate its cell (lung and liver are the section of organ), detect the culture supernatants that is produced with rat CFU-MK mensuration system from suffering from thrombocytopenic rat and obtain marrow, lung, liver and spleen by using P55 antibody.Yet this initial trial does not obtain obvious result.Carried out further trial afterwards, cultivate with collagenase perfusion by the prepared liver cell of liver of using the thrombopenia rat that P55 antibody causes, this is because consider between liver that one piece of report points out rat and the TPO generation certain relation (Siemensma et al. to be arranged, J.Lab.Clin.Med., vol.86, pp.817-833,1975).The gained culture supernatants is added on the WGA-Agarose post, the fraction that fractionation has been adsorbed on Vydac phenyl reversed-phase column then, the TPO in rat plasma source has found closely similar activity in active identical position in rat CFU-MK mensuration system.In normal rat liver cell culture thing supernatant liquor, also found more weak but identical activity.These results show that forcefully liver is one of organ that produces TPO.
(2) the screening rat produces the clone of TPO
Based on The above results, carried out the screening that rat produces the clone of TPO.At first, each clone in the clone in 20 kinds of rat livers source cultivated in succeeding transfer culture liquid matrix separately reach almost converging state, change substratum, continue cultivation 3 days with the identical matrix of nutrient solution separately of having replenished 5%FCS until cell.When having the generation of TPO with mensuration according to top step (1) institute each gained culture supernatants of described method partial purification, found significant TPO activity in the clone in three rat liver parenchyma sources, these three kinds of clones are called McA-RH8994 cell (ATCC preserving number CRL 1602; Becker et al., " Oncodevelopmental Gene Expression " ed.by Fishman and Sell, Academic Press, NY.pp.259-270,1976; Available from Dainippon PharmaceuticalCo., Ltd.), H4-II-E cell (ATCC preserving number CRL 1548; Pitot et al., Nat.Cancer Inst.Monogr., vol.13, pp 229-245,1964; Available from DainipponPharmaceutical Co., Ltd.) with HTC cell (Thompson et al., Proc Natl.Acad.Sci.USA, vol.56, pp.296-303,1966; Available from Dainippon PharmaceuticalCo., Ltd.).
(3) the TPO activity in analyzing in detail McA-RH8994 cell, H4-II-E cell and the HTC cell
To detect by biochemistry and the biological characteristics that these three kinds of rat cells are excretory TPO activated protein, and compare with the TPO in rat plasma source.
With the McA-RH8994 cell suspension in containing α-MEM (-) liquid nutrient medium of 10%FCS and move into 175cm 2The plastics tissue culture flasks in, every bottle contains 1 * 10 6Individual cell.At 5%CO 2After 3 days, change substratum into contain 5%FCS IMDM substratum in 37 ℃ of cultivations in the incubator, and continue to cultivate 3 days, reclaim the culture supernatants of gained.The H4-II-E cell suspension is being contained in the Dulbecco ' s improvement Eagle liquid nutrient medium (glucose 4.5g/l, hereinafter referred to as " DMEM ") of 10%FCS and moving into 175cm 2The plastics tissue culture flasks in, every bottle contains 5 * 10 5Individual cell.At 5%CO 2After 3 days, change substratum into contain 5%FCS IMDM substratum in 37 ℃ of cultivations in the incubator, continue to cultivate 3 days, reclaim the gained culture supernatants.Equally, with the HTC cell suspension in containing the DMEM liquid nutrient medium of 5%FCS and move into 175cm 2The plastics tissue culture flasks in, every bottle contains 2.5 * 10 5Individual cell.At 5%CO 2, after 3 days substratum is changed into the IMDM substratum that contains 5%FCS and continues cultivation 3 days in 37 ℃ of cultivations in the incubator.Reclaim the gained culture supernatants.
Use respectively and go up clear liquid from 2 of these three clones cultivation gained, the TPO that each clone is originated according to the method by XRP purifying TPO described in the embodiment 1-2 carries out partial purification.Its result's roughly situation has hereinafter been described.
At first, make each culture supernatants concentrate about 6 times with ultra-filtration equipment and also change substratum into 20mM Tris-HCl damping fluid (pH 8.0) with the SephadexG-25 post.The gained elutriant adds on the Q-Sepharose FF post, this post is washed with 20mM Tris-HCl (pH8.0), then the fraction of absorption 20mM Tris-Hcl (pH8.0) wash-out that contains 175mM NaCl.The fraction of gained wash-out adds on the WGA-agarose column, and this post is washed with PBS, adsorbed fraction 20mM sodium phosphate (pH 7.2) wash-out that contains 0.2M GlcNAc and 0.15M NaCl.The gained elutriant adds on the TSK-gel AF-BLUE 650MH post, this post is washed adsorbed fraction 2M NaSCN wash-out with the 20mM sodium phosphate (pH 7.2) that contains 1M NaCl.The gained elutriant adds on the Phenyl-Sepharose 6FF/LS post, this post is washed with the 50mM sodium phosphate (pH 7.2) that contains 1.5M ammonium sulfate earlier, again with the 0.8M ammonium sulfate flushing that contains the 36mM sodium phosphate, adsorbed then fraction 20mM sodium phosphate (pH 7.2) wash-out.Gained adsorbed that fraction concentrates and with anti-phase Vydac Protein C4 post (The Separations Group production, catalog number (Cat.No.) 214TP51015; Diameter 1cm; Height of bed 15cm) carries out fractionation.Be about to sample and add to and use in advance on the 20%B equilibrated C4 post, the 1-propyl alcohol with launching to contain among the 0.1%TFA and expansion solvent B in the solvent orange 2 A 0.05%TFA increased to 40%B by the 20%B linear gradient in 90 minutes, carried out effective wash-out with the flow velocity of 1ml/min.Wash-out went out every kind of TPO active protein that derives from these clones when the result was 30-43% in 1-propyl alcohol concentration.
When detecting in each purification step sample TPO with rat CFU-MK mensuration system when active, the result shows that the active TPO that originates with XRP of the TPO of these three kinds of clones has similar pattern (referring to embodiment 1-2).Table 2 has shown the relative reactivity in each purification step that detects with rat CFU-MK mensuration system, activity yied or the like.In addition, when the TPO that detects the elutriant derive from final reversed-phase column with rat CFU-MK system is active, at same peak area discover the TPO that TPO is active and XRP originates of said three clones.When using rat Gp II b/III a +When the colony that CFU-MK separates and the spissated non-adherent cell that goes to obtain in the adhering step carries out reversed-phase column TPO active fraction is measured, active wash-out pattern of Meg-CSF and the active wash-out pattern of TPO closely similar (referring to table 3) with the detection of rat CFU-MK mensuration system.In addition, similar to the TPO situation in XRP source, the TPO activity of each clone in three clone does not form or seldom forms the colony of other clone.
According to the method for describing among the embodiment 1-2, the active fraction that will come from every kind of storage of reversed-phase column adds on the SDS-PAGE post.When detecting the TPO activity when extraction protein from the gel that is produced and with rat CFU-MK mensuration system, the apparent molecular weight of the TPO in the TPO in discovery XRP source, the TPO that the McA-RH8994 cell is originated and H4-II-E cell source is respectively 17,000 to 22,000,33,000 to 39,000 and 31,000 to 38,000, and it is 17,000 to 22,000 and 28 that the TPO in HTC cell source shows apparent molecular weight, 000 to 35,000.
Therefore, these results have shown the TPO protein that is produced by McA-RH8994 cell, H4-II-E cell and HTC cell at the TPO that is being equal to the XRP source aspect its biological characteristics, although its biochemical characteristic is slightly different between mutually on the apparent molecular weight.Significantly find it is that the TPO activated protein molecule that contains in the blood may be this possibility of product that thereon special or unconventional site part digests in the cell of its generation or after its secretion for one of the present invention.It is also pointed out and may have the TPO gene (mRNA and cDNA) with different lengths.

Make up mutant plasmid with Sculptor vitro mutagenesis box (Amersham).The XbaI-HindIII fragment that will derive from the pCFM536/h6T described in the embodiment 42 (1-163) imports with XbaI and HindIII postdigestive Bluescript II SK (-) phagemid carrier (Stratagene, CaliforniaUSA) to obtain plasmid pSKTPO, be transformed into then among the E.coli JM109.(Takara Shuzo Japan) prepares the single stranded DNA that is used for mutagenesis from pSKTPO with helper phage M13KO7.With above-mentioned oligo Nucleotide, by supplier's explanation, will suddenly change imports the TPO gene.By supplier's explanation with dna sequencing box (Applied Biosystems, USA) sequencing analysis and determined the sudden change of TPO fully.
The XbaI-HindIII fragment that will prepare from the pSKTPO of sudden change imports the pCFM536 that digests with XbaI and HindIII.The plasmid pCFM536 that carries mutator gene is transformed among the E.coli#261 to obtain expressing the transformant of TPO derivative gene.
By previous embodiment 43, cultivate E.coli#261 with the pCFM536 conversion of sudden change.The cell granulations of collection purifying body was also stored 1 day in refrigerator at least.Refrigerated cell granulations (3g) is suspended in the 30ml20mM Tris damping fluid (pH 8.5) that contains 10mM EDTA, 10mM DTT and 1mM PMSF.Suspension is placed on ice and with the interval sonic treatment of 1 minute (at least) 5 times.With 15000rpm through the cell of centrifugal collection in 10 minutes through sonic treatment.
Particle suspension in containing the 30ml10mM Tris damping fluid (pH 8.7) of 8M Guanidinium hydrochloride, 5mM EDTA, 1mM PMSF, is added 50mg DTT and makes its reduction.Stir after 1-1.5 hour, the pH of solution is transferred to 5.0, be cooled to 4 ℃ before the dilution then with the HCl of dilution.
With the 1.5L 10mMCAPS damping fluid (pH 10.5) that contains 30% glycerine, 3M urea, 3mM cystamine and 1mM L-Lys dilute sample solution and spending the night gradually.The sample stirring after at least 2 days, was removed precipitation in centrifugal 45 minutes with 8000rpm.With 6m phosphoric acid the pH of solution is transferred to 6.8, dilute 2 times then.With 2 #2 filter paper (φ=90mm, Toyo filter paper, Japan) filtering solution, go up sample then to CM-Sepharose Fast Flow post (on 2.6 * 10cm) (Pharmacia).Wash this post with the 400ml 10mM phosphate buffered saline buffer (pH6.8) that contains 15% glycerine and 1M urea, then with 10mM phosphate buffered saline buffer (pH 7.2) balance that contains 15% glycerine.With linear gradient from the 10mM phosphate buffered saline buffer (pH 7.2) that contains 15% glycerine to the same buffer that contains 0.5MNaCl with the flow velocity of 1.0ml/min elute protein from the post.Absorption value monitoring protein elutriant by 280nm; Determine to contain the fraction of TPO derivative and collect with SDS-PAGE.
After with Centriprep 10 (Amicon) TPO fraction (about 30ml) being concentrated to 2ml, by (3.9 * 150mm) reversed-phase HPLC (Waters) is further purified mutation T PO with μ Bondasphere C4 post.With linear gradient from H 20.05%TFA among the O is to containing 30%CH 3The flow velocity that the 2-propyl alcohol of CN and 0.02%TFA divides with 0.5ml/ was through 40 minutes elute proteins.Under this condition, after about 30 minutes, wash-out goes out the TPO derivative.
In order to carry out biological detection, purified TPO sample was dialysed 2 times to 1L 10mM phosphate buffered saline buffer in 2 days.After being concentrated to about 0.1mg/ml with Centriprep 10 (Amicon), by aforementioned biological activity with M-07e detection system assessment derivative.Find that all mutant all have the h6T of being equal to (1-163), the activity of the reference sample of TPO (seeing Figure 33 and 34).
