{"product_id":"biolegend-686409","title":"Biolegend, 686409, Alexa Fluor® 488 anti-STAT1 Phospho (Ser727) Antibody, 25tests","description":"\u003cp\u003eSTAT1, also known as signal transduction and activator of transcription 1, is a ubiquitously expressed cytoplasmic protein and is activated in response to cytokine signaling, including IFN-α, IFN-γ, EGF, PDGF, and IL-6. Upon activation, STAT1 is phosphorylated by receptor-associated kinases, translocates to the nucleus, and functions as a transcription factor. Two isoforms of STAT1, with apparent molecular weights of 88 and 91 kD, exist as a result of alternative RNA processing. STAT1 is involved in IFN-mediated immune responses, and STAT1-deficient mice are highly sensitive to bacterial and viral infections.\u003cbr\u003e\n25tests\u003cbr\u003e\nVerified Reactivity: Human, Mouse\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Human STAT1 peptide phosphorylated at Ser 727.\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography and conjugated with Alexa Fluor® 488 under optimal conditions.\u003cbr\u003e\nConcentration: Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light.
