Immunofluorescence analysis of Glutamine Synthetase was performed using 70% confluent log phase Hep G2 cells. The cells were fixed with methanol for 5 minutes, and blocked with 2% BSA for 1 hour at room temperature. The cells were labeled with Glutamine Synthetase (8G9) Mouse Monoclonal Antibody (LFMA0095) 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 (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). Cytoskeleton was stained with alpha-Tubulin Monoclonal Antibody (Product# PA516891, 1ug/ml) followed by Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 594 conjugate (A11037) (Panel c: red). Panel d represents the merged image showing cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

p38 MAPK cascade regulates a variety of cellular responses to stress, inflammation and other signals. p38 MAPK is relatively inactive in the nonphosphorylated form and becomes rapidly activated by dual phosphorylation of a Thr-Gly-Tyr motifs. There are four isoforms of p38 MAPK which differ in their tissue expression and affinity for upstream activators and downstream effectors. When cells are exposed to tumor necrosis factor, interleukin-1, heat shock, or other activating stimuli, activation of MAPK kinase-3 and 6 occurs by phosphorylation. Activated MAPK kinase-3/6 phosphorylate each residue of Thr180 and Tyr182 in p38 MAPK. Phospho-p38 MAPK activates ATF-2, CHOP-1, MEF-2 and other transcription factors through phosphorylation.
