This antibody detects both Stat1alpha (91 kDa) and Stat1beta (84 kDa) isoforms. This antibody does not significantly cross-react with the other Stat proteins.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic peptide.\n\u003cb\u003eBackground\u003c\/b\u003e\nThe Stat1 transcription factor is activated in response to a large number of ligands (1) and is essential for responsiveness to IFN-Î± and IFN-Î³ (2,3). Phosphorylation of Stat1 at Tyr701 induces Stat1 dimerization, nuclear translocation, and DNA binding (4). Stat1 protein exists as a pair of isoforms, Stat1Î± (91 kDa) and the splice variant Stat1Î² (84 kDa). In most cells, both isoforms are activated by IFN-Î±, but only Stat1Î± is activated by IFN-Î³. The inappropriate activation of Stat1 occurs in many tumors (5). In addition to tyrosine phosphorylation, Stat1 is also phosphorylated at Ser727 through a p38 mitogen-activated protein kinase (MAPK)-dependent pathway in response to IFN-Î± and other cellular stresses (6). Serine phosphorylation may be required for the maximal induction of Stat1-mediated gene activation.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCANDF7; DKFZp686B04100; IMD31A; IMD31B; IMD31C; ISGF-3; signal transducer and activator of transcription 1; Signal transducer and activator of transcription 1-alpha\/beta; signal transducer and activator of transcription 1, 91kD; signal transducer and activator of transcription 1, 91kDa; signal transducer and activator of transcription-1; STAT1; STAT91; Transcription factor ISGF-3 components p91\/p84\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 84, 91\nSource\/Isotype: Mouse IgG1","brand":"CST","offers":[{"title":"Default Title","offer_id":46800009003177,"sku":"9176S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-9176s","provider":"Iright","version":"1.0","type":"link"}
