    Product Information

    Product Description

    The PathScan® Phospho-p38 MAPK (Thr180/Tyr182) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-p38 MAP kinase phosphorylated at Thr180/Tyr182. A phospho-p38 MAP kinase (Thr180/Tyr182) mouse antibody has been coated onto the microwells. After incubation with cell lysates, phospho-p38 MAP kinase (Thr180/Tyr182) protein is captured by the coated antibody. Following extensive washing, a p38 MAP kinase rabbit detection antibody is added to detect the captured phospho-p38 MAP kinase (Thr180/Tyr182). Anti-rabbit IgG, HRP-linked Antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of phospho-p38 MAP kinase (Thr180/Tyr182).

    *Antibodies in this kit are custom formulations specific to kit.

    Protocol

    Specificity / Sensitivity

    CST's PathScan® Phospho-p38 MAPK (Thr180/Tyr182) Sandwich ELISA Kit detects endogenous levels of p38 MAP kinase phosphorylated at Thr180/Tyr182 in human and mouse cells. As shown in Figure 1, a significant induction of p38 MAP kinase phosphorylation at Thr180/Tyr182 can be detected in HeLa cells using the PathScan® Phospho-p38 MAPK (Thr180/Tyr182) Sandwich ELISA Kit following treatment with anisomycin or UV irradiation. The level of total p38 MAP kinase remains unchanged as shown by western analysis (Figure 1). This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

    Human, Mouse

    Background

    p38 MAP kinase (MAPK), also called RK (1) or CSBP (2), is the mammalian orthologue of the yeast HOG kinase that participates in a signaling cascade controlling cellular responses to cytokines and stress (1-4). Four isoforms of p38 MAPK, p38α, β, γ (also known as Erk6 or SAPK3), and δ (also known as SAPK4) have been identified. Similar to the SAPK/JNK pathway, p38 MAPK is activated by a variety of cellular stresses, including osmotic shock, inflammatory cytokines, lipopolysaccharide (LPS), UV light, and growth factors (1-5). MKK3, MKK6, and SEK activate p38 MAPK by phosphorylation at Thr180 and Tyr182. Activated p38 MAPK has been shown to phosphorylate and activate MAPKAP kinase 2 (3) and to phosphorylate the transcription factors ATF-2 (5), Max (6), and MEF2 (5-8). SB203580 (4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)-imidazole) is a selective inhibitor of p38 MAPK. This compound inhibits the activation of MAPKAPK-2 by p38 MAPK and subsequent phosphorylation of HSP27 (9). SB203580 inhibits p38 MAPK catalytic activity by binding to the ATP-binding pocket, but does not inhibit phosphorylation of p38 MAPK by upstream kinases (10).
