Description
This antibody was cross-adsorbed to unphosphorylated EGFR (Ser-1142) coupled to agarose then affinity purified using phospho-EGFR (Ser-1142) peptide (without carrier). The antibody detects a 180 kDa protein on SDS-PAGE immunoblots of human A431 cells treated with Calyculin A, and does not detect this band after lambda phosphatase treatment.
Immunogen
Phospho-EGFR (Ser-1142) synthetic peptide (coupled to KLH) corresponding to amino acid residues surrounding serine 1142 of human EGFR (ErbB-1). This human EGFR sequence has high homology with rat and mouse EGFR, and is not conserved in other ErbB family members.
