Immunofluorescence analysis of Paxillin was done on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Paxillin (5H11) Mouse Monoclonal Antibody (AHO0492) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300).Panel d is a merged image showing punctuated cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

Paxillin is a focal adhesion protein and a substrate for several tyrosine kinases such as src, FAK, and p210BRC/ABL. The tyrosine phosphorylation of paxillin is affected by conditions that change cell-cell adhesion. Paxillin associates tightly with FAK and Crk through its SH2 domain. This interaction is independent of the extracellular matrix. Although paxillin was initially discovered in fibroblasts, its phosphorylation may also be important during neurite extension during differentiation.
