Anti-EGFR (phospho T678) Antibody

This phosphorylation-state–specific polyclonal reagent from Antibodies.com selectively recognizes the epidermal growth factor receptor (EGFR) only when threonine 678 is phosphorylated, enabling researchers to probe the activation state of this receptor tyrosine kinase rather than its total abundance. The antibody was raised in rabbit, is provided as an IgG preparation, and is supplied unconjugated in a 200 µl volume suitable for routine Western Blot workflows on lysates derived from Human cells and primary tissues, with documented reactivity limited to the Human target. By distinguishing the phospho-T678 modification from other EGFR phosphorylation events, it supports studies of downstream signaling context, kinase pathway dissection, and comparative analyses between basal and stimulated receptor states in research-use immunoblotting experiments.
