NEUTRALIZING ASSAY KITS

NEUTRALIZING ASSAY KITS

Neutralizing antibody assay kits are essential tools used to measure the functional antibody response against viruses.

Unlike general antibody tests that only detect binding antibodies, these kits specifically assess neutralizing antibodies—the type of antibodies capable of blocking the virus from binding to host cells.

Our product line includes a wide range of variant-specific neutralization assay kits, targeting key SARS-CoV-2 variants such as B.1.1.7, B.1.351, P.1, B.1.617.2 (Delta), B.1.1.529 (Omicron), BA.4 & BA.5, BA.2.12.1, XBB.1.5, and more.

Each kit is based on the Spike RBD (Receptor Binding Domain) or Spike Trimer protein, mimicking the viral entry mechanism.​
