Abstract

The present invention relates to the method that a kind of amount with increase prepares cytokinin, wherein under different temperature and/or pH value condition, finish and induce and production process.

Description

A kind of method that increases yield of cytokins
The present invention relates to prepare with the productive rate that has improved the method for cytokinin, wherein to induce with producing be to finish under different temperature and pH value condition.
Cytokinin between living organism tissue and cell function connect each other and adjusting aspect play an important role." cytokinin " (" Cytokin ") comprises that producing justacrine by viable cell learns active molecule or molecule group to all the tool lives in its surrounding environment.For example, comprising interleukin-, Interferon, rabbit (IFNs), lipocortin (lipocartin), tumour necrosis factor etc.
Under suitably inducible factor participated in, viable cell can also produce cytokinin in vitro.Above-mentioned inducible factor can be virus, phytohaemagglutinin, mitogen, phorbol ester, ionophore, synthetic Yeast Nucleic Acid etc.As seen, can pass through the natural biologically active substance of proper method suitability for industrialized production.
Also can promptly use genetic manipulation to prepare cytokinin, wherein the humans and animals cell be placed nutrient solution to make it under the effect of inductor, to produce cytokinin, and then from substratum, reclaim cytokinin by so-called natural method.Relevant preparation method is record to some extent in the literature: prepare lipocortin (referring to B.Rothhut etc., FEBS Lett.219,169(1987)) as using the glucocorticoid inducible agent; Use the PMA inductor to prepare B-cell stimulating factor (IL-4) (referring to J.HuLi etc., J.EXP.Med., 165,157(1987)); Use the concanavalin A inductor to prepare interleukin II (referring to K.Kato etc., Biochem.Biophys.Res.Commun.127,182(1985)); And use the Sendai virus inductor to prepare methods such as interferon-alpha (referring to K.Cantell etc., Methods Enzymol.72,29(1981)).
The common feature of aforesaid method is that induce and the production process of cytokinin carry out under identical conditions.
Invention is based on such understanding: promptly under only inductive condition, also can occur producing the inhibition factor earlier, and this factor can be avoided by suitable adjustment envrionment conditions.
Use method of the present invention, can under conditions in vitro, increase the productive rate of the cytokinin of various cell generations significantly.
Usually can be by handling corresponding cell with one or more inductors, and then the insulation certain hour prepares cytokinin.Available currently known methods is received the cell agonist that is secreted in the nutritive medium back and forth.
The objective of the invention is by reducing the effect of cell kinetin synthesis inhibitoroy factor, thereby improve the output of cytokinin.
The method according to this invention can change heat-retaining condition at interval by reasonable time, stoping the influence of supressor, thereby improves the output of cytokinin greatly.
We find that after exponential phase, delaying cytokinin synthetic biological process can more strengthen at the cytokinin synthetic.Since exponential phase, it is less that cytokinin produces the susceptibility that heat-retaining condition is changed, and also more less than the suffered restraining effect of the above-mentioned building-up process that slows down.Therefore, can and select the suitable time to prolong the production interval by the appropriate change heat-retaining condition.
The following example will be illustrated the present invention in more detail.
Do not mentioning the place of regulating the pH value, the pH value is a physiological value, promptly 7.2~7.4.
Embodiment 1
Increase human leukocyte interferon-'s productive rate by the pH value that changes insulation.
Remove the red corpuscle that pollutes with 0.83% ammonium chloride solution through haemolysis several times, obtain the buffy coat (Buffy coat, the isolating white corpuscle component that is rich in from fresh human blood) of purifying, then with the white corpuscle of gained with 1 * 10 7The concentration of individual cell/ml is suspended in and contains inorganic salt, glucose and 1mg/ml and do not have in the proper nutrition liquid of gamma Globulin human serum.In above-mentioned suspension, add the 200IU/ml human leukocyte interferon-, mixing solutions is incubated 2 hours down in 37 ℃.And then in cell suspending liquid, add the Sendai virus of 100HA unit/ml, and with mixing solutions in 37 ℃ of insulations 2 hours down.
After 2 hours, in the bottle that contains cell suspending liquid, add a certain amount of Tris-HCl damping fluid, with its P HValue is transferred to 7, is incubated 20 hours then.In nutrient solution, isolate white corpuscle through centrifugal.The disease-resistant inflexible Ъ of the Interferon, rabbit crude product that so makes scoops up 00 with a dustpan, and 000IU/ml that is to say than not transferring P with damping fluid HBe worth the prepared interferon anti-reflecting virus high twice of tiring.
Embodiment 2
Change holding temperature and P HValue is to increase the productive rate of human leukocyte IFN-and interleukin II.
Can in same cell culture, prepare IFN-and interleukin II simultaneously.
White corpuscle that is made by fresh buffy coat or exhausted white corpuscle when formerly preparing Interferon, rabbit all can be used for this production process.Can be by the cell suspension of the preparation of the method described in the embodiment 1.
With white corpuscle with 1 * 10 7~2 * 10 7The dope of cell/ml is suspended in and contains 1mg/ml and do not have in the known nutrient solution of gamma Globulin human serum.Can add down 10~20 μ g/ml concanavalin As or 1~10 μ g/ml phytohaemagglutinin or 20~10 μ g/ml mesereine in 37 ℃, or 0.5~2 μ g A 23187 ionophores or 5~30ng/ml phorbol tetradecanoic acid acetic ester are induced.Add inductor after 3 hours, will contain leukocytic bottle and place 30 ℃ of thermostat containers, P HBe transferred to 7 these mixing solutionss of back insulation.After the insulation, centrifugal from the nutritive medium that contains IFN-and interleukin II (IL-2), to isolate cell.
Antiviral the tiring of IFN-is 15,000IU/ml, and antiviral the tiring of interleukin II is 1,300IU/ml.These potency ratios are not transferred P with damping fluid under 37 ℃ of steady temperatures HTiring of the product that makes is high 2~2.5 times.
Embodiment 3
Change holding temperature to increase the productive rate of lipocortin
With the red corpuscle of 0.83% ammonium chloride solution, by the buffy coat that makes purifying in the fresh human blood through the pollution of haemolysis removal several times.Then with the pure white cell of gained with 1 * 10 7The concentration of individual cell/ml is suspended in the nutrient solution that does not contain serum, is incubated 2 hours down with the processing of 1 μ M dexamethasone and in 37 ℃.Again holding temperature is transferred to 30~32 ℃ and is continued insulation 15 to 20 hours.Then from nutritive medium, remove leucocyte-removing with centrifuging.The gained supernatant liquor is the raw product of lipocortin, and the inflammation that its on Carrageenan is brought out has very strong anti-inflammatory action.The lipocortin crude product that makes under non-constant temperature is higher 2~2.5 times than the anti-inflammatory action of the lipocortin that makes under steady temperature.The size of anti-inflammatory action is by the intravital carrageenin test determination of mouse by the described method of people such as Winter (Pract.Soc.Exp.Biol.Med., 111,644(1962)).
