Immunofluorescence analysis of Phospho-p44 MAPK + p42 MAPK pThr202 + pTyr204 Antibody was done on 70% confluent log phase A549 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 Phospho-p44 MAPK + p42 MAPK pThr202 + pTyr204 Antibody (368800) at 1µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa flour 488 Goat Anti-Rabbit IgG Secondary Antibody (A11008) at a dilution of 1:400 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 594 Phalloidin (A12381). Panel d is a merged image showing cytoplasmic and nuclear localization. Panel e is a no primary antibody control. The images were captured at 40X magnification.

This antibody is predicted to react with Xenopus and zebrafish based on 100% sequence homology.
36-8800 is specific for the ~42k - 44k ERK/MAPK phosphorylated at Thr202 and Tyr204. Immunolabeling is blocked by the phosphopeptide used as antigen but not by the corresponding dephosphopeptide. The immunolabeling is completely eliminated by lambda-phosphatase.
Extracellular signal-regulated kinase 2 (Erk2) is also known as mitogen activated protein kinase 2, microtubule-associated protein-2 kinase MAP kinase 2, p42-MAPK or EGF receptor T669 (ERT1). Mek2 activates Erk2 by phosphorylation of neighbouring threonine-183 and tyrosine-185 residues. Erk2, a serine-threonine kinase phosphorylates microtubule associated protein-2 and myelin basic protein. This kinase is an important proximal componant of the MAP kinase pathway involved in transmitting the signals from growth factors, neurotransmitters and hormones at the cell surface to the transcriptional events in the nucleus.
