STAT3 in Human PBMCs. STAT3 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) using 15 µg/mL Sheep Anti-Human STAT3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF17991) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained (green).

Detection of Human STAT3 by Western Blot. Western blot shows lysates of NIH‑3T3 mouse embryonic fibroblast cell line, Raji human Burkitt's lymphoma cell line, and Daudi human Burkitt's lymphoma cell line. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human STAT3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF17991) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for STAT3 at approximately 92 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Signal Transducer and Activator of Transcription (STAT) proteins are transcription factors activated in response to cytokine, growth factor, or hormone receptor signaling. Janus kinases (JAKs) phosphorylate STAT proteins and induce dimerization. Homo- or heterodimers translocate to the nucleus where they bind to DNA and activate transcription.
