Immunocytochemistry - Anti-FAK (phospho Y861) antibody (AB4804)

Immunofluorescence analysis of FAK [pY861] was done on 70% confluent log phase A-549 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 labelled with ab4804 at 1 : 250 dilution in 1% BSA and incubated for 3 hours at room temperature and then labelled with a Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate at a dilution of 1 : 2000 for 45 minutes at room temperature (Panel a : green). Nuclei (Panel b : blue) were stained with DAPI. F-actin (Panel c : red) was stained with Rhodamine Phalloidin at a 1 : 300 dilution. Panel d is a merged image showing localization of target protein at focal adhesions. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Western blot - Anti-FAK (phospho Y861) antibody (AB4804)

Peptide Competition : Cell extracts prepared from chick embryo fibroblasts expressing FAK and plated on fibronectin were resolved by SDS-PAGE on a 10% Tris-glycine gel. The proteins then were transferred to nitrocellulose and incubated with 0.50 μg/mL ab4804 antibody, following prior incubation with : (1) the phosphopeptide immunogen, (2) a generic phosphotyrosine containing peptide, (3) the non-phosphorylated peptide corresponding to the phosphopeptide, and (4) no peptide. After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar detection method. The data show that only the phosphopeptide corresponding to this site blocks the antibody signal, demonstrating the specificity of the ab4804 antibody for this phosphorylated residue.
