Biolegend, 943401, Purified anti-EGFR Phospho (Tyr845) Recombinant Antibody, 25μg

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.
25μg
Verified Reactivity: Human
Antibody Type: Recombinant
Host Species: Mouse
Immunogen: Synthetic peptide corresponding to human EGFR phosphorylated at tyrosine 845
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide
Preparation: The antibody was purified by affinity chromatography.
Concentration: 0.5 mg/mL
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
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.
