The Mouse Anti-Human Antibody (MAHA) ELISA Assay Kit is produced for the quantitative determination of mouse anti-human antibody (MAHA) levels in mouse serum or plasma samples. It detects both MAHA-IgG and MAHA-IgM subtypes. The test is used for detection of mice with positive MAHA that may affect prescribed studies involving humanized monoclonal antibody, which is essential to avoid misleading immunoassay test results and conclusion.
