ERBB2 belongs to the protein kinase superfamily, Tyr protein kinase family and EGF receptor subfamily. It contains a protein kinase domain. ERBB2 is widely expressed in epithelial cells, and amplification and/or overexpression of ErbB2 has been reported associated with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate and ovarian cancers. Rat ERBB2 is an essential component of a neuregulin-receptor complex, although neuregulins do not interact with it alone. ErbB2 mediates signalling pathways which involve mitogen-activated protein kinase and phosphatidylinositol-3 kinase, this receptor plays a key role in development, cell proliferation and differentiation.

< 1.0 EU per μg of the protein as determined by the LAL method.

Lyophilized from a 0.2 μm filtered solution of PBS, 5% Trehalose, 4M Urea, pH 7.4.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Recombinant Rat Receptor tyrosine-protein kinase ErbB-2 is produced by our E.coli expression system and the target gene encoding Ala67-Val323 is expressed with a 6His tag at the C-terminus.
