Detection of Human Phospho-STAT5a/b (Y694/Y699) by Western Blot.

Western blot shows lysates of Daudi human Burkitt's lymphoma cell line and HeLa human cervical epithelial carcinoma cell line untreated (-) or treated (+) with 500 U/mL Recombinant Human IFN-aA (Catalog # 11100-1) for 20 minutes. PVDF membrane was probed with 0.1 µg/mL of Rabbit Anti-Human Phospho-STAT5a/b (Y694/Y699) Monoclonal Antibody (Catalog # MAB41901) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for STAT5a/b at approximately 95 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Phospho-STAT5a/b (Y694/Y699) in IFN alpha-treated Daudi Human Cell Line by Flow Cytometry.

Daudi human Burkitt's lymphoma cell line was unstimulated (open histogram) or treated with 500 U/mL rhIFN-alpha for 20 minutes (filled histogram) and stained with Rabbit anti-Human Phospho-STAT5a/b (Y694/Y699) Molyclonal Antibody (Catalog # MAB41901) followed by APC-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # F0111). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with methanol. View our protocol for Staining Intracellular Molecules.

Background: STAT5a/b

Signal transduction and activator of transcription 5 (STAT5) is a member of the Jak/STAT signal transduction pathway and is activated by a variety of cytokines (IL-22, IL-6, IFN-alpha). STAT5 has two isoforms (A and B) that share 93% amino acid identity and bind the DNA consensus site TTCN₃GAA. STAT5 mediates cytokine signaling by acting as a signal transducer in the cytoplasm and, upon phosphorylation, translocates to the nucleus and activates transcription of specific genes. STAT5 is involved in a wide array of biological processes ranging from regulating apoptosis to adult mammary gland proliferation, differentiation, and survival.
