SARS-CoV-2 Related Kit Products

Background

High-quality recombinant antigen proteins and kit products are critical in accelerating the research and development of anti-SARS-CoV-2 drugs and vaccines.

ACROBiosystems has developed a series of kit products using its high-quality SARS-CoV-2 antigen proteins to improve the efficiency of anti-SARS-CoV-2 drugs and vaccines development. These kit products include SARS-CoV-2 antibody titer serologic assay kits, antigen detection kits, inhibitor screening kits and antigen pre-coated plates and these products can be used for SARS-CoV-2 neutralizing antibody screening, antibody detection and antigen detection.

>>>Accelerated Progress Towards Vaccine Efficacy Evaluation

An increasingly number of people are getting vaccinated to acquire protection against SARS-CoV-2, meanwhile the original wild type virus is evolving to acquire increased fitness that may help evade vaccine-induced immune surveillance. In face of this “Red Queen”1 challenge, how strong the current vaccine protection is against the circulating and emerging variants of the virus becomes a primary concern. Although multiple neutralizing antibody tests have been developed to evaluate vaccine effectiveness against the wild type virus, an important assessment tool to perform this function against the variants is missing.

Now, the gap between what we have and what we need is closed by the successful development of neutralizing antibody titer kits specifically designed for three major SARS-CoV-2 variants, namely B.1.1.7 (the U.K. variant), B.1.351 (South African variant) and P.1 (Brazilian variant). These kits are based on competitive ELISA assays to detect the presence of neutralizing/blocking antibodies in human serum that can specifically inhibit the binding of mutated spike trimer or spike RBD protein to its human receptor ACE2. With verified high sensitivity and specificity, these kits are convenient to use under standard lab condition and can test many samples at the same time.
