The antibody has been negatively preadsorbed using (i) a non phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated epidermal growth factor receptor (EGFR), and (ii) a generic tyrosine phosphorylated peptide to remove antibody that is reactive with phosphotyrosine, irrespective of the sequence. The final product is generated by affinity chromatography using an EGFR-derived peptide that is phosphorylated at tyrosine 1068.

Immunocytochemistry/ Immunofluorescence - Anti-EGFR (phospho Y1068) antibody (ab5644)
Immunofluorescence analysis of A431 (Human epidermoid carcinoma cell line) cells labeling EGFR with ab5644 at 1/100 dilution, followed by Goat anti-rabbit IgG (H+L) Superclonal, Alexa Fluor® 488 conjugate was used as the secondary antibody at 1/2000 dilution (Panel a). Nuclei (Panel b) were stained with SlowFade® Gold Antifade Mountant with DAPI. F-actin (Panel c) was stained with Rhodamine Phalloidin. Panel (d) represents the merged image showing membrane localization. Panel (e) represents cells treated with antagonist, Afatinib (1µM for 6hrs) followed by EGF (200 ng/ml for 10 minutes), showing no Phospho-EGFR staining. Panel (f) shows untreated cells with no signal. Panel (g) represents control cells with no primary antibody to assess background.
The cells (in 70% confluent log phase treated with 200ng/ml of EGF for 10 minutes) were fixed with 4% paraformaldehyde for 10 minutes; permeabilized with 0.1% Triton X-100 for 10 minutes and blocked with 1% BSA for hour at room temperature. The images were captured at 60X magnification.

Western blot analysis using ab5644 shows increased expression of proteins phosphorylated at the tyrosine residues in A-431 and A549 cell lines upon EGF treatment and pre-treatment with EGFR-antagonists, Gefitinib and Afatinib. This results in inhibition of Phospho-EGFR in A-431 and A549 cell lines
