The development of in vitro diagnostics (IVD) kits based on immunoassays, such as lateral flow tests (LFT) and enzyme-linked immunosorbent assay (ELISA) relies on the availability of high-quality matched pairs of antibodies to capture and detect target analytes. It can be a challenge to find off-the-shelf and confirmed antibody pairs with the high sensitivity, specificity, purity, and stability needed to ensure an IVD kit meets performance requirements. We have taken the guesswork out of finding antibodies for diagnostic raw materials, offering only the best-confirmed pairs.
