Data Examples
Detection of STAT2 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, filled histogram) for 20 minutes was stained with Rabbit Anti-Human Phospho-STAT2 (Y689) Monoclonal Antibody (Catalog # MAB2890), followed by Fluorescein-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # F0112). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with 90% methanol.
Detection of Human Phospho-STAT2 (Y689) by Western Blot. Western blot shows lysates of Daudi human Burkitt's lymphoma cell line untreated (-) or treated (+) with 500 U/mL Recombinant Human IFN‑ alpha A (Catalog # 11100-1) for 20 minutes. PVDF membrane was probed with a 1:1000 dilution of Rabbit Anti-Human Phospho-STAT2 (Y689) Monoclonal Antibody (Catalog # MAB2890) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-STAT2 (Y689) at approximately 113 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Phospho-STAT2 (Y689) by Simple WesternTM. Simple Western lane view shows lysates of Daudi human Burkitt's lymphoma cell line untreated (-) or treated (+) with 500 U/mL Recombinant Human IFN‑ alpha A (Catalog # 11100-1) for 20 minutes, loaded at 0.2 mg/mL. A specific band was detected for Phospho-STAT2 (Y689) at approximately 111 kDa (as indicated) using 1:100 dilution of Rabbit Anti-Human Phospho-STAT2 (Y689) Monoclonal Antibody (Catalog # MAB2890). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: STAT2

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.
