General Description
QuickAntibody™ is a proprietary novel adjuvant designed specifically for the preparation of monoclonal as well as polyclonal antibodies in mice. Compared with the conventional Freund’s adjuvant, it has the unique features of fewer immunizations, less antigen dosage, quick antibody induction, higher antibody titers, higher antibody affinity, no destroy of natural antigen conformation, no epitope competition from other proteins, and easy to use.
User Guidelines
1. QuickAntibody™ can achieve antigen-sparing effect through fewer immunizations (only two injections) and less antigen dosage per injection. Recommended antigen dosage is: (1) 5~20μg per injection for low immunogenic antigens such as recombinant subunit proteins or peptide-carrier conjugates; (2) 1~5μg per injection for high immunogenic antigens such as inactivated viruses or recombinant virus-like particles.
2. QuickAntibody™ can induce a quick immune response, generating high titers as well as high affinity of antibodies. Whatever used for monoclonal as well as polyclonal antibody preparation, it requires only two immunizations within 3 weeks, and high titers of antibodies with ELISA titers up to 1:10000~1:10000000 could be elicited in the fifth week.
3. In contrast to Freund’s adjuvant, QuickAntibody™ doesn’t destroy natural antigen conformation, which facilitates the generation of monoclonal antibodies against conformational epitopes.
4. In contrast to complete Freund’s adjuvant, QuickAntibody™ doesn’t have protein antigens, which eliminates the epitope competition from adjuvant-derived proteins.
5. In contrast to the tedious emulsification required by Freund’s adjuvant, QuickAntibody™ is provided as a ready-to-use solution that can be easily mixed with any antigen before animal immunization.
6. In contrast to the tedious foot-pad or intra-spleen immunization usually used in monoclonal antibody protocols, QuickAntibody™ can be conveniently used through intra-muscular injection.
7. QuickAntibody™ is most useful in preparing murine polyclonal antibodies. In contrast to conventional rabbit polyclonal antibody preparation, which is usually provided by companies as customer-service, with QuickAntibody™ any laboratory can easily generate 1ml of high quality murine polyclonal antibodies within 5 weeks by simply immunizing 5 mice. (Note: 1ml of high quality murine polyclonal antibodies should fulfill most experimental requirements.)
8. QuickAntibody™ is shipped at ambient temperature and stored at 2-8ºC (Do not freeze!). The adjuvant is stable for up to 6 months at 2-8ºC.
Product Name: QuickAntibody™-Mouse 2W
Cat No: KX0210043
Size: 1 ml
Intended use: rapid generation of murine polyclonal antibodies (ELISA titers up to 1:1000~1:10000 or higher) by two injections within 2 weeks.
Immunization Protocol
1. Dilute the antigen with saline to 2-fold final concentration (50ul per injection).
Note: Recommended antigen dosage is: (1) 5~20μg per injection for low immunogenic antigens such as recombinant subunit proteins or peptide-carrier conjugates; (2) 1~5μg per injection for high immunogenic antigens such as inactivated viruses or recombinant virus-like particles.
2. Mix the adjuvant by vortexing, sterilely remove the required volume (50ul per injection), and mix with the antigen at 1:1 ratio (V/V) as quick as possible.
Note: It is normal to see precipitation in the adjuvant.
3. Inject 100μl of the antigen/adjuvant mixture into quadriceps muscles of both hind legs.
Note: It is normal to see precipitation in the antigen/adjuvant mixture. Please mix well before drawing into syringe and inject as quick as possible after drawing into syringe.
4. Bleed from tail tips on day 14 post-priming and measure the antibody titers by ELISA. ELISA titers should be in the range of 1:1000~1:10000. After that the whole serum can be collected.
