ErbB2/Her2 Antibody (4D5-8 (trastuzumab)) - Chimeric - Azide and BSA Free

Immunohistochemistry-Paraffin: ErbB2/Her2 Antibody (4D5-8 (trastuzumab)) - Chimeric [NBP2-52639] - Immunohistochemical Anti-erbB-2 (Her-2/neu) staining of paraffin embedded human breast tissue using the rabbit-chimeric version of 4D5-8 (trastuzumab) (NBP2-52639). Primary antibody incubation with NBP2-52639 was carried out at 4 ug/ml for 30 minutes. Samples were then incubated with an anti-rabbit IgG HRP secondary antibody for 20 mins followed by DAB (3,3'-diaminobenzidine), and counter-staining with haemotoxylin. Weak membrane staining exclusively of ductal epithelial cells may be observed. Recommended concentration, 4-6 ug/ml.

ErbB2/Her2 Antibody (4D5-8 (trastuzumab)) - Chimeric - Azide and BSA Free Summary

• Additional Information: Recombinant Monoclonal Antibody.
• Immunogen: A431 cells (human epidermoid carcinoma) (over)expressing EGFR.
• Specificity: Oncogenic protein Her-2/neu (erbB-2), a member of the family of epidermal growth factor (EGF) receptors, overexpressed in 30% of invasive breast cancers and 70% of ductal carcinomata in situ, in a small percentage of melanomas, and in other malignancies originating from various organs, including ovary, kidney, colon, and bladder.
• Isotype: IgG Kappa
• Clonality: Monoclonal
• Host: Rabbit
• Gene: ERBB2
• Purity: Protein A purified

Applications/Dilutions

• Dilutions:
  • CyTOF-ready
  • ELISA 1:100 - 1:2000
  • Flow Cytometry 1:10 - 1:1000
  • Immunohistochemistry 1:10 - 1:500
  • Immunohistochemistry-Paraffin
• Application Notes: This antibody is Cytof ready. This chimeric rabbit antibody was made using the variable domain sequences of the original Human IgG1 format, for improved compatibility with existing reagents, assays and techniques. This antibody binds to ErbB2/Her2 has therapeutic indications particularly in the treatment of breast cancer (c.f. Herceptin). It can also be used to detect HER-2 by flow cytometry or IHC (Glazyrin 2007).

Background

ErbB2/HER2 is one of the four members of the ErbB receptor family of transmembrane receptor-like tyrosine kinases (1). The kinase activity of ErbB2 can be activated without ligand if it is overexpressed, and by association with other ErbB proteins (2). Overexpression of ErbB2 is detected in almost 40% of human breast cancers (3). Binding of c-Cbl ubiquitin ligase to Tyr1112 of ErbB2 leads to poly-ubiquitination of ErbB2 and enhances its degradation (4). ErbB2 is one of the major targets for the treatment of breast cancer and other carcinomas.
