Detect SARS-CoV-2 Neutralization Antibodies by ELISA

Measure functional neutralizing antibodies (NAbs) in 1 hour with the new cPASS™ kit

Conventional neutralizing antibody tests, such as Virus neutralization tests (VNT), Pseudo-virus neutralization test (pVNT) or Plaque reduction neutralization tests (PRNT) can be time-consuming and in particular, require access to strict biosafety containment such as BSL3 for testing.

Discover a new, ideal alternative solution - which you can use in any laboratory setting!

The cPass™ SARS-CoV-2 Neutralization Antibody Detection Kit is the first COVID-19 detection kit capable of detecting neutralizing antibodies that are typically the best predictor of immunity.

  • Simple, convenient and fast - obtain results in one hour
  • Scalable - 96-well plate format (12 strips of 8 wells) compatible with automation
  • Versatile - Compatible with serum, plasma and media
  • Sensitive & specific - Species & isotype independent with no cross-reactivity with flu and other viral diseases (cross-reactivity only seen with SARS-CoV-1)

What is the principle of the cPass™ SARS-CoV-2 Neutralization Antibody detection ELISA Kit?

The kit detects circulating neutralizing antibodies against SARS-CoV-2 that block the interaction between the receptor binding domain (RBD) of the viral spike glycoprotein with the ACE2 cell surface receptor.

Which applications can I use the cPASS™ kit for?

  • Viral spike glycoprotein (RBD)/ACE2 receptor interaction studies
  • Vaccine and Biologics development - leading to production of COVID-19 neutralizing antibodies in human or animal samples
  • COVID-19 Epidemiology Studies - investigations of sero-prevalence, assessment of herd immunity, longevity of protective immunity, efficacy of vaccine candidates as well as tracking infection in animals.

Why should I choose the cPASS™ kit?

cPass™ Neutralization Antibody ELISA test Virus Neutralization Assay
  • Fast, scalable and automatable
  • Works in any laboratory setting
  • Can be done at high throughput
  • More consistent

  • Requires strict safety conditions - BSL3
  • Takes days to perform
  • Requires high level expertise to read
  • Expensive and not scalable
