Immunofluorescence analysis of EGFR [pY1045] was done on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with EGFR [pY1045] Mouse monoclonal Antibody (44782M) at 2µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Flour 488 Rabbit Anti-Mouse IgG Secondary Antibody (A11059) at a dilution of 1:400 for 30 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor 594 Phalloidin (A12381). Panel d is a merged image showing cytoplasmic localization. Panel e shows no primary antibody control. The images were captured at 20X magnification.

Epidermal Growth Factor Receptor (EGFR) is a 175 kDa transmembrane glycoprotein belonging to tyrosine kinase superfamily. It acts as a receptor for epidermal growth factor (EGF) family proteins. Binding of EGFR to its ligands causes autophosphorylation of tyrosine kinase followed by activation of signal transduction pathways connected to cell proliferation and differentiation. Tyrosine 1068 present within the cytoplasmic domain of the receptor is a major autophosphorylation site that allows binding of Grb2 and activation of the Ras-Raf-ERK1 and ERK2 signaling pathway.
