      • Mouse anti Human ErbB2 antibody recognizes ErbB2, also known as c-erb B2/neu protein, herstatin, metastatic lymph node gene 19 protein, neuro/glioblastoma derived oncogene homolog, neuroblastoma/glioblastoma derived oncogene homolog, p185erbB2, proto-oncogene Neu, proto-oncogene c-ErbB-2, receptor tyrosine-protein kinase erbB-2, tyrosine kinase-type cell surface receptor HER2, v-erb-b2 avian erythroblastic leukemia viral oncoprotein 2, v-erb-b2 erythroblastic leukemia viral oncogene homolog 2 and neuro/glioblastoma derived oncogene homolog.

        Encoded by the ERBB2 gene, ErbB2 is a member of the epidermal growth factor (EGF) receptor family of receptor tyrosine kinases. This protein has no ligand binding domain of its own and therefore cannot bind growth factors. However, it does bind tightly to other ligand-bound EGF receptor family members to form a heterodimer, stabilizing ligand binding and enhancing kinase-mediated activation of downstream signalling pathways, such as those involving mitogen-activated protein kinase and phosphatidylinositol-3 kinase. Allelic variations at amino acid positions 654 and 655 of isoform a (positions 624 and 625 of isoform b) have been reported, with the most common allele, Ile654/Ile655, shown here. Amplification and/or overexpression of ERBB2 has been reported in numerous cancers, including breast and ovarian tumors. Alternative splicing results in several additional transcript variants, some encoding different isoforms and others that have not been fully characterized (provided by RefSeq, Jul 2008).

        Mouse anti Human ErbB2 antibody detects a band of 185 kDa. The antibody has been extensively validated for western blotting using whole cell lysates. This antibody is available with a positive control lysate, in a smaller trial size, and as a standalone antibody.
