Immunohistochemistry: MBS241896 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for MBS241896 was determined to be 5 ug/ml. Western Blot: 0.5-2 ug/ml detects c-erbB-2 in RIPA lysates from A431, MDA, MCF-7, LNCap, and c-erbB-2 transfected 3T3/NIH cells. Immunoprecipitation: 4 ug immunoprecipitated c-erbB-2 from 500 ug of A431, LNCap, and c-erbB- 2 transfected 3T3/NIH RIPA lysate. IHC-paraffin: 5 ug/ml. Western Blot: 0.5-2ug/ml

Rinse slides in 1X TBST -1 minute @ RT. Apply alkaline phosphatase chromogen substrate - 30 minutes @ RT. Wash slides in distilled water - 1 minute @ RT. Dehydrate: . (This method should only be used if the chromogen substrate is alcohol insoluble (e.g. Vector Red, DAB) . Wash slides in 2 changes of 80% alcohol - 1 minute each @ RT. Wash slides in 2 changes of 95% alcohol - 1 minute each @ RT. Wash slides in 3 changes of 100% alcohol - 1 minute each @ RT. Wash slides in 3 changes of xylene - 1 minute each @ RT. Apply coverslip

Family: Protein Kinase. Subfamily: EGF Receptor

A tyrosine kinase receptor in the EGF-receptor family. ErbB2 does not bind ligand on its own, but acts as an amplifier in heterodimers with ErbB1, (EGFR), ErbB3, or ErbB4. Amplification of the ErbB2 gene and overexpression of ErbB2 protein is associated with breast cancer (~25% of cases), and anti-ErbB2 therapeutics (e. g. Herceptin, an anti-ErbB2 monoclonal antibody) are sometimes effective in treating these cases. Overexpression of ErbB2 has also been indicated as a factor in prostate cancer.

This gene encodes 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 this gene 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]

HER2: a proto-oncogenic receptor tyrosine kinase of the EGFR family. Essential component of a neuregulin-receptor complex, although neuregulins do not interact with it alone. Not activated by EGF, TGF- alpha and amphiregulin. Amplified in breast cancer. Overexpression induces constitutive activity, and the gene is amplified or overexpressed in up to 30% of breast cancers, correlating with poor survival. The antibody Herceptin is approved for treatment of metastatic breast cancer with HER2 amplification/overexpression. Somatic mutations seen in 4% of lung cancers and also in breast, gastric, ovarian cancer and glioblastoma. One SNP shows predisposition to breast and gastric cancer.
