SoFastAntibody-Rabbit8W

Use:

Rabbit polyclonal antibodies are prepared by the standard 8-week 3-dose immunization program, and the ELISA titer (Cutoff value of 0.1000) can reach 1:10,000-1:10,000,000.

Note:

Transport at room temperature, store 2-8oC, sterile access, valid for 12 months. (Do not freeze!)

Usage:

1. Dilute the antigen with normal saline to 2 times the final concentration (prepared according to the dosage of 100μl per injection). Note: The recommended dosage of antigen is (1) subunit protein antigen with weak immunogenicity 20-50μg per injection; (2) Inactivated whole virus or whole bacteria and virus-like particle antigen with strong immunogenicity 5-10μg per injection.

2. Fully mix the adjuvant, and take out the required dosage (100μl per injection) under aseptic conditions and quickly mix the antigen with the volume ratio of 1:1. Note: Precipitation of this adjuvant is a normal phenomenon, and the faster the mixed operation with antigen, the better.

3. Immunized rabbits were injected through the calf muscle of the back leg, 200μl was injected into each rabbit. Remarks: (1) It is normal for this adjuvant to precipitate after mixing with antigen. It should be thoroughly mixed before being pumped into the needle and injected as soon as possible after being pumped into the needle; (2) Customers can also choose subcutaneous injection or intradermal injection for immunization according to their own experimental habits.

4. On day 21 and day 42, the immunization was strengthened by 1 dose in the same way. Remarks: Each time the adjuvant and antigen are used, the injection site is the same as the primary immunization.

5. On the 52-56 days, a small amount of blood was taken for ELISA determination, and the antibody titer should be in the range of 1:10,000-1:100,000, and then a large amount of blood could be taken.

Compared with the conventional Fredrin adjuvant, SoFastAntibody immune adjuvant has many advantages, such as short immune cycle, less injection times, no need for emulsification, low amount of antigen, high antibody titer, high antibody affinity, easy to obtain conformational epitopes of antibodies, etc., detailed as follows:

1.SoFastAntibody requires only two doses of immunization, whether used for monoclonal or polyclonal antibody preparation, which can reduce immunization times compared with Fredrin adjuvant.

2.SoFastAntibody can greatly save the total amount of antigen by reducing the number of immunization shots and reducing the amount of antigen per shot. The recommended dosage of antigen is (1) 5-50μg per dose of subunit protein antigen with weak immunogenicity (usually 5-20μg for mice and 20-50μg for rabbits); (2) Inactivated whole virus or whole bacteria and virus-like particle antigen with strong immunogenicity 1-10μg per injection (usually 1-5μg for mice and 5-10μg for rabbits).

3.SoFastAntibody has fast antibody production, high antibody titer and high antibody affinity. For example, the standard immunization procedure, whether used for monoclonal or polyclonal antibody preparation, requires only two doses of immunization over three weeks, usually obtaining a high affinity antibody level of 1:10,000-1:10,000,000 with an ELISA titer (Cutoff value of 0.1000) at week 5.

4.SoFastAntibody does not destroy the natural conformation of the antigen, so it is easy to screen and obtain monoclonal antibodies against the epitope of the conformational type of antigen, which is an important feature that Fredrin adjuvant does not have.

5.SoFastAntibody is a class of water-soluble adjuvant, which does not require the complex emulsification process of Freudenstein's adjuvant when used, and the antigen and adjuvant can be used in immunizing animals simply by mixing.

6.SoFastAntibody uses muscle immune pathway, which is much easier to use than foot pad immunization or intrasplenic immunization used in the routine preparation of mouse monoclonal antibodies.

7. An important use of SoFastAntibody is that it can be easily used to produce mouse polyclonal antibodies. The conventional polyclonal antibody preparation mainly uses rabbits, which not only has many immunization times, large amount of antigen and slow antibody production, but also needs to entrust special units for preparation due to high technical requirements. With SoFastAntibody immune adjuvant, any laboratory animal can easily and quickly prepare mouse polyclonal antibodies, and the standard immunization procedure requires simply immunizing five mice to obtain 1ml of high-quality mouse polyclonal antibodies after five weeks. (This adjuvant is strongly recommended for the preparation of mouse polyclonal antibodies, and 1ml of high-quality mouse polyclonal antibodies is sufficient to meet the experimental needs of most users, including for enzym-linked immunization, western blotting, flow cytometry, immunohistochemistry and immunoprecipitation, etc.)

8.SoFastAntibody is recommended to be transported at room temperature, stored at 2~8oC, sterile access, and valid for 12 months.
