General description
Monoclonal Anti-c-erbB-2 (HER-2, Neu) (mouse IgG1 isotype) is derived from the (human epidermal growth factor receptor 2) HER2-96 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c mouse immunized with a purified extracellular domain of human erbB-2, from transfected cells. The human erbB-2 oncogen (also known as HER2, HER-2 or neu) encodes a transmembrane growth factor orphan receptor with a M.W. of 185 kDa (p185). The complete protein consists of an internal cytoplasmic structure with tyrosine kinase activity, a short hydrophobic transmembrane section and an extracellular ligand-binding domain (ECD).
Immunogen
purified extracellular domain of human erbB-2 from transfected cells.
Application
Monoclonal Anti-c-erbB-2 antibody produced in mouse has been used in :
- enzyme linked immunosorbent assay (ELISA)
- immunoprecipitation
- immunohistochemistry
- studies on receptor internalization, phosphorylation, ligand binding and tumor growth inhibition
Biochem/physiol Actions
Erb-b2 receptor tyrosine kinase 2 (ErbB-2) has a pivotal role in signal transduction, where it can stimulate the signal even in the absence of ligand by forming heterodimers with erbB-1/EGF-R, erbB-3, and erbB-4 and hence can modifies ligand affinity. Thus, erbB-2 alters the intracellular responses elicited by EGF and NDF. This control is due to the fact that erbB-2, when in complex with another erbB family receptor, decelerates the rate of ligand dissociation. Therefore, erbB-2 may act as a signalling subunit for other receptors rather than a true growth factor receptor. Because overexpression of the erbB-2 proto-oncogene is frequently associated with an aggressive clinical course of certain human adenocarcinomas, the encoded protein is an attractive target for immunotherapy. Indeed, antibodies to erbB-2 were found to block the crosstalk with growth factor receptors. In addition, receptor overexpression is considered a predictor of poor survival and short time of relapse.
