Description
Technical field
The present invention relates to Fluorescent antib field, specially a kind of immune antiboidy and preparation method thereof.
Background technique
Blood group antibody is generally divided into two classes: natural antibody and immune antiboidy, and general natural antibody is IgM, and immune antiboidy is
IgG.1. IgM class antibody can be aggregated the red blood cell with corresponding antigens in brine media, this kind of antibody be mainly ABO and
P, MN, Lewis antibody is often natural antibody.Energy activating complement, occurs intravascular hemolysis.Such antibody cannot penetrate placenta, and
Its optimal reaction temperature is 4 DEG C so being called cold antibody.2. IgG class antibody is corresponding to having in brine media in most cases
The red blood cell of antigen is not aggregated, and is only just aggregated in colloidal medium, enzyme or antiglobulin, cohesion amine medium, this
Class antibody is mainly the blood group antibodies such as Rh, Kidd, Duffy.Usual situation is generated by immune (blood transfusion, gestation, organ transplant)
Antibody, also known as immune antiboidy.Mostly occur extravascular hemolysis.37 DEG C of such antibody optimal reaction temperature is so be called warm antibodies.
Current immune antiboidy is not ideal enough to the immune stage level of animal during preparation, and to dynamic
Object not enough standardizes when taking sample blood, is easy so that obtained immune antiboidy is not pure and mild contaminated, specificity is low, potency is low and affine
Power is low.For this purpose, the invention proposes a kind of immune antiboidies and preparation method thereof.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of immune antiboidy and preparation method thereof, have by rabbit
Son carries out the immune of three phases, can prepare the immune antiboidy of high-purity, takes sample in vivo from rabbit by specification
Blood, so that the advantages that immune antiboidy taken out not by germ contamination, improves the purity of immune antiboidy, solves immune antiboidy
It is not ideal enough to the immune stage level of animal during preparation, and not enough standardized when taking sample blood to animal, hold
It is easier that obtained immune antiboidy is not pure and mild contaminated, specific low, the low problem low with affinity of potency.
(2) technical solution
In order to achieve the above object, the invention provides the following technical scheme: a kind of immune antiboidy, by being taken out out of rabbit body
Sample blood is taken to carry out repeatedly immune generated antibody.
A kind of preparation method of immune antiboidy, the specific steps are as follows:
Step 1: the selection of animal selects 2-3 months or more rabbits, immune to perform label, then carries out a point cage again and raises
It supports；
Step 2: antigen (cellulase) is diluted to 4mg/ml, can be mixed and made into emulsion with adjuvant by the selection of antigen
It is immune for rabbit；
Step 3: the preparation of adjuvant and antigen emulsion, adjuvant Split completely: light mineral oil (Valelinum Liquidum) 8.5ml, sheep
Hair rouge 1.5ul inactivates tubercle bacillus 10mg, the preparation of antigen emulsion；
(1) finish: mineral oil and lanolin mix in proportion, finish are used as after 8 pounds of sterilizings in 20 minutes of high pressure, using preceding micro-
Fire melts；
(2) aqua: inactivation tubercle bacillus 1mg/ul+ antigen 4mg/ml；
(3) finish and aqua 1:1 mixing；
Step 4: it is immune, then the subcutaneous multi-point injection of arteria auricularis of rabbit, every 0.1m1, immune for the first time: experimental group exists
Add the antigen of adjuvant in rabbit body,
A group 5 (there is yellow on head): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml phosphoric acid buffer
Liquid；
B group 5 (there is yellow in tail portion): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml2mg/ml fiber
Plain south liquid；
C group 8 (there is yellow at middle part): the every subcutaneous multi-point injections of rabbit arteria auricularis, total injection 0.4ml add the anti-of adjuvant
Former emulsion；
Second is immune: adjuvant antigen is not added in experimental group rabbit within the 3rd week,
A group 5 (there is yellow on head): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml phosphoric acid buffer
Liquid；
B group 5 (there is yellow in tail portion): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml2mg/ml fiber
Plain alcohol liquid；
C group 8 (there is yellow at middle part): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml2mg/ml fiber
Plain enzyme solution；
Third time is immune: second is immune 1 week latter, and adjuvant antigen is not added in experimental group rabbit,
A group 5 (there is yellow on head): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml phosphoric acid buffer
Liquid；
B group 5 (there is yellow in tail portion): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml2mg/ml fiber
Plain enzyme solution；
C group 8 (there is yellow at middle part): the every subcutaneous multi-point injections of rabbit arteria auricularis amount to injection 0.4ml2mg/ml fiber
Plain alcohol liquid；
Step 5: sero-fast preparation, third time is immune, after a week, from the arteria auricularis of rabbit is subcutaneous or cardiac sample product
Blood, the blood of collection is placed in 1h or so at room temperature, after solidification, sets at 4 DEG C, and serum is precipitated in (being sure not to freeze) overnight, is centrifuged,
Serum is sucked out in aseptic condition in 4000rpa, 10min, is then carried out with the antigen (having epitope 2) with same epitope anti-
It answers, to remove non-specific antibody, the specific immunity for being directed to (epitope 2) is anti-.
Preferably, the hybrid mode of the finish and aqua is grinding or syringe mixing.
Preferably, the serum being sucked out in the step 5 is dispensed (0.05~0.2ul), stores in -40 DEG C or less refrigerators,
Or it is stored in 4 DEG C of refrigerators after freeze-drying and saves.
Preferably, the inactivation tubercle bacillus and antigen are final concentration.
Preferably, described the step of taking sample blood are as follows: the ear of rabbit is exposed to outside boxes and baskets, can also be caught and be exempted from by another people
Body cuts off the hair of ear edge, smears auricle with a little dimethylbenzene, after 30s, ear blood vessel dilatation, hyperemia gently draw have sharp ears with hand, with list
The knife blade of face shaver or point quickly cuts ear artery, and blood flows out, and collects 30~40ml every time, then uses
Cotton balls hemostasis by compression washes away dimethylbenzene after blood coagulation, after two weeks, can in another ear bloodletting, this method can repeated multiple times bloodletting, put
It strictly to be carried out by sterility requirements during blood.
(3) beneficial effect
Compared with prior art, the present invention provides a kind of immune antiboidy and preparation method thereof, have it is following the utility model has the advantages that
1, immune antiboidy and preparation method thereof is immunized by carrying out three phases to rabbit, can be prepared high-purity
The immune antiboidy of degree, high specificity, potency are high and affinity is strong, sample blood are taken in vivo from rabbit by specification, so that taking
Immune antiboidy out by germ contamination, does not improve the purity of immune antiboidy.
