Immunofluorescence analysis of Phospho-c-Fos pThr232 was done on 70% confluent log phase HeLa cells treated with 20 ng of EGF for 10 minutes. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with Phospho-c-Fos pThr232 Rabbit Polyclonal Antibody (44280G) at 2 ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) 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 nuclear localization. Panel e is untreated cell with no signal. Panel f represents control cells with no primary antibody to assess background. The images were captured at 60X magnification.

c-FOS is a nuclear phosphoprotein which forms a tight but non-covalently linked complex with the JUN/AP-1 transcription factor. It has a critical function in regulating the development of cells destined to form and maintain the skeleton, and is thought to have an important role in signal transduction, cell proliferation and differentiation.
