Catalog #: A2010010 – 10 mg

The presence in human serum of Human Anti-Mouse antibodies (HAMA) is a major concern in immunoassays. 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. The provided HAMA Blocking Reagent specifically binds to HAMA, minimizing their interference and significantly reducing the number of false positives. Simply spike our HAMA Blocking Reagent into your immunoassay reagent(s) to 5-50 ug/mL (optimum concentration is assay dependent).
