in-cell Western analysis for phospho p38 (T180/Y182)
Fast Activated Cell-based ELISA (FACE™) Kits provide a simple, sensitive method for detecting protein phosphorylation directly in the cell, without making extracts or performing electrophoresis and membrane blotting. These 96-well, high-throughput assays are available in both colorimetric and chemiluminescent formats for over 20 different targets (see list at right). For complete details, click the FACE™ Method tab below.
FACE p38 Kits provide 96 rxns each of 2 antibodies that enable you to monitor and compare the levels of both phosphorylated and total p38. The phospho-p38 antibody recognizes the p38 alpha, beta, gamma and delta isoforms only when phosphorylated at Thr180 and Tyr182. The total-p38 antibody recognizes p38 proteins regardless of their phosphorylation states. Click the p38 Info tab below for data and more information.

Figure 1: Colorimetric measurement of phosphorylated p38.
The phospho-p38 antibody is specific for phosphorylated p38 and was raised against a peptide phosphorylated on residues that correspond to the sequence surrounding Thr180 and Tyr182 of human p38. It recognizes p38 alpha, beta, gamma and delta isoforms. The total-p38 antibody recognizes p38 MAPK regardless of its phosphorylation state.
p38 MAPK Overview
p38 MAP kinase is a member of the Mitogen Activated Protein Kinase (MAPK) family of proteins. It was first identified in a screen for drugs inhibiting tumor necrosis factor-mediated inflammatory responses. p38 MAPK is activated in response to a variety of stimuli including growth hormones, ligands for G-protein coupled receptors, inflammatory cytokines and stresses such as osmotic shock and heat shock. Because of its critical role in inflammation regulation and stress response, p38 MAPK is of great interest in both basic and therapeutic research, making high-throughput study methods in demand.
