Description

Mouse Monoclonal Antibody

C-erbB-3, a glycoprotein of 160kDa, is a member of the type 1 growth factor receptor subfamily which also includes c-erbB-2 (HER2/neu), c-erbB-4 and the epidermal growth factor receptor (EGFR, c-erbB-1). Members of this receptor subfamily mediate the proliferation and differentiation of normal cells. They have a common structure consisting of an extracellular domain, a transmembrane region, and a cytoplasmic sequence. The extracellular regions contain two cysteine-rich domains, and the intracellular regions have sequence homology to known tyrosine kinases. C-erbB-3 is expressed in tissues from the digestive, urinary and respiratory tracts, the circulatory system, and female and male reproductive organs. c-erb B-3 is undetectable in hematopoietic tissue and cell lines derived from hematopoietic tumors. Cellular localization has been described as cytoplasmic and/or membrane, and nuclear. The level and pattern of c-erbB-3 expression varies widely in both normal and tumor tissues.
Clone RTJ.1 recognizes an epitope in the cytoplasmic domain of the human c-erbB-3 protein. It does not react with the EGF receptor or c-erbB-2. A synthetic peptide (referred to as 49.3) from the cytoplasmic domain of human c-erbB-3 protein was used as immunogen. RTJ.1 identifies a 160kDa band corresponding to c-erbB-3 by western blot analysis and immunoprecipitation. RTJ.1 may also react with two additional, unidentified higher molecular weight bands by immunoprecipitation and western blot analysis. These bands are likely to be non-specific, as they were not detected with a polyclonal antibody raised against the same immunogen. Because two additional bands were observed, the specificity of RTJ.1 for immunohistochemistry was analyzed by comparing staining results to those obtained using three polyclonal antibodies also raised against 49.3. Identical staining results were obtained using RTJ.1 and all three polyclonal antibodies. These results validated the use of RTJ.1 for immunohistochemical analysis of c-erbB-3.
