CST, 61259W2, Phospho-p38 MAPK (Thr180/Tyr182) (3D7) Rabbit Monoclonal Antibody (SignalFlex™ Alexa Fluor® 750 Conjugate)

Monoclonal Antibody for studying p38-alpha MAPK (Thr180/Tyr182) phosphate/p38-delta MAPK (Thr180/Tyr182) phosphate/p38-gamma MAPK (Thr183/Tyr185) phosphate/p38-beta MAPK (Thr180/Tyr182) phosphate. Highly specific and rigorously validated in-house, Phospho-p38 MAPK (Thr180/Tyr182) (3D7) Rabbit Monoclonal Antibody (SignalFlex^™ Alexa Fluor^® 750 Conjugate) (CST #61259) is ready to ship. Product Usage Information SignalFlex™ conjugates are produced using highly validated Cell Signaling Technology ® primary antibodies and conjugation methods that have been rigorously tested, ensuring high-quality conjugates and lot-to-lot consistency. These conjugates are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. However, they are not tested on specific assays. Optimal dilutions/concentrations should be determined by the end user. When performing flow cytometry, we recommend using an isotype control conjugate at the same concentration as the antibody conjugate. Storage Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze. Specificity / Sensitivity Phospho-p38 MAPK (Thr180/Tyr182) (3D7) Rabbit Monoclonal Antibody (SignalFlex™ Alexa Fluor Species Reactivity: Human, Mouse, Rat, Monkey, D. melanogaster, Pig, S. cerevisiae Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr180/Tyr182 of human p38 MAPK. 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).
