Immunofluorescence analysis of GAPDH was done on 70% confluent log phase U2OS 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 GAPDH Mouse Monoclonal Antibody (A21994) at 1 µg/mL 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 with 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.

Glyceraldehyde 3 phosphate dehydrogenase (GAPDH) is an enzyme involved in glycolysis. In addition to this role, it is involved in other cellular processes ranging from membrane fusion, neuronal apoptosis to cancer. GAPDH is expressed at high levels in most tissues and is therefore useful as protein loading control in western blot analysis. Additionally, the antigen is conserved in most eukaryotes.
