Anti-ERBB2 Antibody

This rabbit polyclonal reagent from Antibodies.com targets the receptor tyrosine kinase ERBB2 (also called HER2/neu), a 185 kDa transmembrane glycoprotein of the ErbB family that drives proliferative signaling and is frequently amplified in breast cancer research samples. The unconjugated IgG is supplied as 200 µl of stock and supports both western blot and immunohistochemistry workflows on human, mouse, and rat specimens, allowing laboratories to screen receptor status across panels of normal and tumor tissue. The polyclonal host response yields recognition of multiple epitopes across the intracellular and extracellular domains, useful when probing truncated or mutant receptor variants that monoclonal reagents can miss. Each preparation is validated for WB band detection at the expected molecular weight and for IHC signal on fixed tissue sections, with secondary detection reagents supplied separately by the end user.
