ACROBiosystems has launched matched antibody pairs that are specifically designed and screened for antigen detection kit development, which are suitable for different diagnostic assays, such as chemiluminescent immunoassay, ELISA, gold immunochromatography assay, etc. The sensitivity of the sandwich ELISA can be as low as 12 pg/mL in the verification study using recombinant antigens. In addition, the antibody pairs have been verified using inactivated virus samples. The titer, which was determined using our LFA assay, is as low as 5 TCID₅₀.

Facing increasingly complex mutations, scientists are concerned whether the new mutants could be detected by rapid antigen tests. ACROBiosystems successfully verified that our high-sensitive antibody pair (Cat. No. S1N-M12A1/S1N-M13A1) can detect the latest SARS-CoV-2 variants.

These antibodies were recommended for antigen detection by double antibody sandwich.

Testing the levels of neutralizing antibodies against S protein in serum samples is critical in determining the efficacy of vaccines as well as a diagnostic measure of past infections. With the beginning of large-scale immunization with multiple vaccines and the rise of mutant variants, close monitoring of neutralizing antibodies in population and the impact of virus mutation is necessary for effective immunization campaign. ACROBiosystems has developed multiple high quality RBD proteins and ACE2 proteins to support neutralizing antibody test development.
