Anti-ERBB4 Antibody

ERBB4 (also called HER4) is a receptor tyrosine kinase of the ErbB/EGFR family that mediates cell growth, differentiation, and survival through ligand-dependent signaling. This rabbit polyclonal antibody from Antibodies.com was raised against ERBB4 and is supplied as an unconjugated IgG preparation in a 200 µl vial.

The antibody recognizes human and mouse ERBB4 and is validated for Western blot detection of the receptor. It binds the ErbB4 protein in cell lysates and tissue extracts, supporting studies of receptor activation, downstream PI3K/AKT and MAPK signaling, and expression patterns in developmental and cancer research contexts.

Working in research-use applications, this unconjugated IgG reagent pairs with HRP- or fluorescent-labeled secondary antibodies in standard immunoblotting workflows. For routine handling, aliquot the antibody into smaller volumes to minimize repeated freeze-thaw cycles and preserve binding activity across multiple experiments.
