The cPass™ SARS-CoV-2 Neutralization Antibody Detection Kit is a blocking ELISA

detection tool. Using purified receptor binding domain (RBD) protein from the viral spike

(S) protein and the host cell receptor ACE2, this test is designed to mimic the virus-host

interaction by direct protein-protein interaction in a test tube or a well of an ELISA plate.

The highly specific interaction can then be neutralized, the same manner as in a

conventional Virus Neutralization Test (VNT).

The kit contains two key components: the Horseradish peroxidase (HRP) conjugated

recombinant SARS-CoV-2 RBD fragment (HRP-RBD) and the human ACE2 receptor

protein (hACE2). The protein-protein interaction between HRP-RBD and hACE2 can be

blocked by neutralizing antibodies against SARS-CoV-2 RBD.
