Antigens & Antibodies for Diagnostic Kit Development
 
    Committed to high sensitivity & specificity

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.

Verification study using inactivated virus

The titer is as low as 5 TCID₅₀ in the verification study using inactivated virus.

Detect RBD mutants with high sensitivity

Detection of SARS-CoV-2 S protein RBD mutants （Cat.No. SPD-C52Hn, SRD-C52H3, SPD-C52Hp）by Sandwich ELISA

Detect SARS-CoV-2 antigen with high specificity

Demonstration of the specificity of Anti-SARS-CoV-2 N antibody pairs (Cat. No. NUN-S46 & Cat. No. NUN-S47) to the Nucleocapsid protein.

High batch-to-batch consistency

Demonstration of the Batch to Batch Consistency of Anti-SARS-CoV-2 Spike S1 Antibody, Chimeric Mab (Cat. No. S1N-M122) to the S1 protein.

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.
