ab126453 is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in cell lysates. By determining phosphorylated p38 alpha protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blot analysis.
This Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the measurement of human phospho-p38 alpha (Thr180/Tyr182) and total p38 alpha (help normalize the results of phospho-p38 alpha from different cell lysate being compared). An anti-p38 alpha (Thr180/Tyr182) (half plate, red marker on left side) and anti-total p38 alpha antibody (half plate, black marker on right side) has been coated onto a 96-well plate. Samples are pipetted into the wells and phosphorylated (left side) and total (right side) p38 alpha present in a sample is bound to the wells by the immobilized antibody. The wells are washed and rabbit anti p38 alpha is used to detect phosphorylated or total p38 alpha. After washing away unbound antibody, HRP-conjugated anti-rabbit IgG is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of p38 alpha (Thr180/Tyr182) or total p38 alpha bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Get results in 90 minutes with p38 MAPK alpha (pT180/Y182 + Total) ELISA Kit (ab176664) from our SimpleStep ELISA® range.
Responds to activation by environmental stress, pro-inflammatory cytokines and lipopolysaccharide (LPS) by phosphorylating a number of transcription factors, such as ELK1 and ATF2 and several downstream kinases, such as MAPKAPK2 and MAPKAPK5. Plays a critical role in the production of some cytokines, for example IL-6. May play a role in stabilization of EPO mRNA during hypoxic stress. Isoform Mxi2 activation is stimulated by mitogens and oxidative stress and only poorly phosphorylates ELK1 and ATF2. Isoform Exip may play a role in the early onset of apoptosis.
Brain, heart, placenta, pancreas and skeletal muscle. Expressed to a lesser extent in lung, liver and kidney.
Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. Contains 1 protein kinase domain.
The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
Dually phosphorylated on Thr-180 and Tyr-182, which activates the enzyme. Phosphorylated upon DNA damage, probably by ATM or ATR.
