Biolegend, 661001, Purified anti-STAT1 Antibody, 25μg

STAT1, 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.
