QA19A93_PURE_EGFR_Phospho_Tyr845_Antibody_020221
Whole cell extracts (15 µg protein) from untreated (-) and recombinant human EGF-treated (+) (Cat. No. 585506) A-431 cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 µg/mL (1:500 dilution) purified anti-EGFR Phospho (Tyr845) recombinant antibody (clone QA19A93) for two hours at room temperature. Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG antibody (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-β-actin antibody (Cat. No. 664804) was used as a loading control at a 1:25000 dilution (lower). Total EGFR loading was confirmed using purified anti-EGFR antibody (clone A19002A) (Cat. No. 933902) at 0.05 µg/mL.

Description

Epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase that links extracellular mitogenic ligand binding to complex downstream signaling cascades. Initial ligand binding results in receptor oligomerization and autophosphorylation of multiple tyrosine residues within cytosolic domains of the protein. Phosphorylation at tyrosine 845, which is found in the kinase activation loop, stabilizes the active conformation and leads to the recruitment of adaptor proteins and other downstream effectors. EGFR stimulation leads to activation of RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCγ-PKC and STAT signaling cascades, and constitutive activation of the receptor promotes tumorigenesis in multiple cancers.

Application

WB - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.5 - 1.0 µg/mL. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This clone was tested for ICC on A-431 cells treated with or without EGF. We failed to detect any EGFR Phospho (Tyr845) staining using the following fixation and permeabilization methods:

  • 4% PFA plus Triton X-100
  • 4% PFA plus methanol
  • Methanol only
This clone failed to immunoprecipitate EGFR Phospho (Tyr845) from whole cell extracts prepared from EGF-stimulated A-431 cells.

This recombinant antibody clone is derived from clone A18028A.

This clone is predicted to recognize the region corresponding to EGFR Phospho (Tyr845) in both rat (Tyr846) and mouse (Tyr847) orthologs due to complete sequence conservation with the immunizing peptide.
