Used in biomedical research to detect and quantify levels of the human ErbB2 (Her2) protein in cell lysates, serum, or other biological samples. This ELISA kit is particularly valuable in cancer research, especially for studying breast, ovarian, and gastric cancers where Her2 overexpression is linked to tumor progression. It enables researchers to assess Her2 activation states, monitor response to targeted therapies like trastuzumab, and evaluate biomarker expression in preclinical studies. The assay supports high-throughput analysis with high sensitivity and specificity, making it essential in both academic and pharmaceutical research settings.
