Anti-ErbB2 (V777A), monoclonal

Concentration: 0.2 mg/ml. Formulation: PBS (without Mg2+ and Ca2+), pH 7.4, 150 mM NaCl, 50% glycerol. The ErbB family is composed of four plasma membrane-bound receptor tyrosine kinases. Amplification or over-expression of the ERBB2 gene occurs in approximately 30% of breast cancers. HER2 is encoded by ERBB2, a known proto-oncogene located at the long arm of human chromosome 17(17q21-q22). HER2 proteins have been shown to form clusters in cell membranes that may play a role in tumorigenesis. Mutations of ErbB2 protein, including V777A, have been indicated in human cancers.
