GenScript cPass™ SARS-CoV-2 Neutralization Antibody Kit

Catalog No. L00847

GenScript’s cPass™ SARS-CoV-2 Neutralization Antibody Kit quickly and accurately detects and measures neutralization response in a sample against the SARS-CoV-2 virus.


60 mins

to measure functional neutralizing antibodies (NAbs)





96 Tests

Per Kit

The sVNT test is faster, easier, more scalable, and readily automatable compared to the traditional neutralizing antibody tests, such as virus neutralization test (VNT), pseudo-virus neutralization test (pVNT), and plaque reduction neutralization test (PRNT).

The Benefits




High Sensitivity & Specificity


Safe and


TAT: 24 hours
Or Less

Reducing the Chromogenic Reaction


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 cPass SARS-CoV-2 Neutralizing Antibody Kit is a blocking ELISA detection tool, which mimics the virus neutralization process. The test uses the interaction between viral protein-receptor protein to mimic the virus infection of a live cell, which is monitored by a chromogenic reaction. When there are neutralizing antibodies in the patient sera, they will block the specific protein-protein interaction and hence reducing the chromogenic reaction, mimicking the virus neutralization process.
