Detection of Phospho-STAT2 (Y689) in Daudi Human Cell Line by Flow Cytometry.
Daudi human Burkitt's lymphoma cell line untreated (open histogram) or treated with 500 U/mL Recombinant Human IFN‑ alpha A (Catalog # 11100-1) for 20 minutes was stained with Rabbit Anti-Human STAT2 Alexa Fluor® 488‑conjugated Monoclonal Antibody (Catalog # IC8627G, filled histogram) or isotype control antibody (Catalog # IC105G, not shown). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with 90% methanol.

STAT2 (signal transducer and activator of transcription 2) is a 113 kDa member of the STAT family of cytoplasmic transcription factors. STAT members generally mediate cytokine, growth factor and hormone receptor signal transduction. STAT2 is associated with type I ( alpha - and beta -) interferon signaling. All STATs contain an N‑terminal oligomerization domain, a DNA-binding domain, and an SH2-association region. STAT2 is phosphorylated at Y689 by receptor-associated Janus kinases (JAKs) leading to STAT2 dimerization and subsequent translocation to the nucleus to activate gene transcription.
