Product Overview
This rabbit polyclonal antibody targets epidermal growth factor receptor (gene EGFR) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 134.3 kDa, and the supplier reports an observed band at about 180 kDa.
Epidermal growth factor receptor (EGFR, also called ErbB1 or HER1) is a receptor tyrosine kinase activated by EGF, TGF-α and related ligands. Ligand binding triggers receptor dimerization and activation of RAS/MAPK, PI3K/AKT and other pathways that drive proliferation and survival, and EGFR is a major target in cancer research.

Immunogen
Recombinant human EGFR fragment (Asn36–Asn497), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places epidermal growth factor receptor in the cell membrane, endoplasmic reticulum membrane, Golgi apparatus membrane and nuclear membrane. Tissue expression noted by UniProt (human): Ubiquitously expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
