In response to cytokines and growth factors; STAT family members are phosphorylated by the receptor associated kinases; and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. STAT1 can be activated by various ligands; including interferon-alpha; interferon-gamma; EGF; PDGF and IL6. It is a signal transducer and transcription activator that mediates cellular responses to interferons (IFNs); cytokine KITLG\/SCF and other cytokines and growth factors. The phosphorylated STATs dimerize; associate with ISGF3G\/IRF-9 to form a complex termed ISGF3 transcription factor; that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of interferon stimulated genes; which drive the cell in an antiviral state. In response to type II IFN (IFN-gamma); STAT1 is tyrosine- and serine-phosphorylated. It then forms a homodimer termed IFN-gamma-activated factor (GAF); migrates into the nucleus and binds to the IFN gamma activated sequence (GAS) to drive the expression of the target genes; inducing a cellular antiviral state. STAT1 becomes activated in response to KITLG\/SCF and KIT signaling and may mediate cellular responses to activated FGFR1; FGFR2; FGFR3 and FGFR4. Defects in STAT1 can cause STAT1 deficiency complete and familial candidiasis type 7.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: \u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e: Not validated for activity\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e: Met 1-Val 712\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:  \u0026gt; 92 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFormulation\u003c\/b\u003e: Lyophilized from sterile 20mM Tris, 500mM NaCl, pH 7.4\u003cbr\u003eNormally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.\u003cbr\u003ePlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Please refer to the printed manual for detailed information.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEndotoxin\u003c\/b\u003e:  \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCalculated MW\u003c\/b\u003e: 111 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: 105 kDa\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":47972847059044,"sku":"PKSH030783","price":1224.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_3cbec129-5e17-4cca-9b2f-3bedd50f4db6.jpg?v=1772200162","url":"https:\/\/www.genebiosystems.com\/products\/recombinant-human-stat1-protein-his-gst-tag","provider":"GeneBio ","version":"1.0","type":"link"}
