Detection of Human Phospho-STAT1 (Y701) by Western Blot.
Western blot shows lysates of Daudi human Burkitt's lymphoma cell line untreated (-) or treated (+) with Recombinant Human IFN‑ alpha A (Catalog # 11100-1) for 20 minutes. PVDF membrane was probed with 1:1000 dilution of Rabbit Anti-Human Phospho-STAT1 (Y701) Monoclonal Antibody (Catalog # MAB2894) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-STAT1 (Y701) at approximately 90 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

STAT1 (signal transducer and activator of transcription #1) is an 88 kDa member of the STAT family of cytoplasmic transcription factors. STAT members generally mediate cytokine, growth factor and hormone receptor signal transduction. STAT1 is associated with type I and II interferon signaling. All STATs contain an N-terminal oligomerization domain, a DNA-binding domain, and an SH2-association region. STAT1 is phosphorylated at Y701 by receptor-associated Janus kinases (JAKs) leading to STAT1 dimerization and subsequent translocation to the nucleus to activate gene transcription.
