Applications Key:  W=Western Blotting  IHC-P=Immunohistochemistry (Paraffin)
Reactivity Key:  H=Human
Species cross-reactivity is determined by Western blot.

Protocols

Specificity / Sensitivity

HER4/ErbB4 (111B2) Rabbit mAb detects transfected levels of ErbB4 protein. This antibody does not cross-react with other ErbB family members.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human ErbB4.

Western Blotting

Western Blotting

Western blot analysis of cell extracts from various cell lines, using HER4/ErbB4 (83B10) Rabbit mAb (IHC Specific). This antibody specifically detects overexpressed HER4/ErbB4 proteins in tranfected Cos cells, but does not cross-react with EGFR (A431 and MDA-468), ErbB2 (MDA-453) and ErbB3 (MCF7 and T47D) proteins.

Background

The HER/ErbB receptor tyrosine kinase family has been implicated in normal development, cardiac function and cancer (1,2). HER4/ErbB4, like other family members, has four ectodomains, a single transmembrane domain and a cytoplasmic tail containing the active tyrosine kinase domain (3). By binding to neuregulins and/or EGF family ligands, ErbB4 forms either a homodimer or heterodimer with other ErbB family members, which results in receptor activation and signaling (3). ErbB4 is ubiquitously expressed with the highest expression occurring in brain and heart. The expression of ErbB4 in breast cancer, pediatric brain cancer and other types of carcinomas has been reported suggesting that ErbB4 expression is involved in both normal tissue development and carcinogenesis (3).
