HAMA Interference Kit for Assay Validation


Catalog #: K2010009
A ready-to-use kit to test Human Anti-Mouse Antibodies (HAMA) interference in immunoassays. The kit includes five serum-based HAMA-positive serum samples (PS1 to PS5) with HAMA concentrations of up to 100 ng/mL (as established by a HAMA ELISA assay) as well as a serum-based HAMA-negative sample (NS) that serve as a control (no HAMA). The kit also includes a protocol to test HAMA Interference in a typical immunoassay. HAMA Interference Kit is specially formulated to suppress dilution and matrix issues during testing.

About HAMA

For decades, immunoassays have relied heavily on mouse antibodies for the detection of various analytes. The accuracy of these assays can, however, suffer dramatically when patient samples contains human anti-mouse antibodies. Indeed, HAMA are often associated with inaccurate results and false positives because they can bind to both capture and detection antibodies and can generate non-specific immunoassay signals. This so-called HAMA problem is especially noticeable in patients receiving mouse antibodies therapies. Assessing the tolerance of an immunoassay to HAMA is a corner stone in assay validation.
