Anti-ErbB2/HER2 (K676) Antibody

Antibodies.com provides a rabbit polyclonal antibody targeting ErbB2/HER2 at the K676 epitope region. The unconjugated reagent detects endogenous levels of ErbB2/HER2 protein and has been validated for Western blot (WB), immunohistochemistry (IHC), and immunofluorescence (ICC/IF) workflows, with reactivity confirmed against Human, Mouse, and Rat samples.

The antibody was raised against a synthetic peptide corresponding to amino acids 641–690 of human ErbB2/HER2 and is supplied at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2. Affinity purification using the epitope-specific immunogen produced a purity greater than 95% as assessed by SDS-PAGE. The targeted ErbB2 protein has a reported molecular weight of approximately 138,185 kDa.
