NKX6.1 in Human Pancreas. NKX6.1 was detected in immersion fixed paraffin-embedded sections of human pancreas using Goat Anti-Human/Mouse NKX6.1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5857) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Mouse NKX6.1 by Western Blot. Western blot shows lysates of beta TC‑6 mouse beta cell insulinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse NKX6.1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5857) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for NKX6.1 at approximately 46 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Mouse NKX6.1 by Simple WesternTM. Simple Western lane view shows lysates of beta TC‑6 mouse beta cell insulinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for NKX6.1 at approximately 54 kDa (as indicated) using 10 µg/mL of Goat Anti-Human/Mouse NKX6.1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5857) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

NKX6.1 (NK homeobox factor 6.1; also NKX6A) is a 39‑46 kDa member of the homeodomain family of transcription factors. It is expressed in embryonic ventral neural tube where it drives neural progenitors to form motoneurons and V2-type interneurons. It is also expressed in both fetal and neonatal pancreas where it promotes a beta -cell phenotype. NKX6.1 exhibits both transcriptional gene repression (NKX6.2 and Dbx2) and activation (cyclin A2 and B1). When overexpressed, it induces beta -cell mitosis. Human NKX6.1 is 367 amino acids (aa) in length. It contains a repressor region composed of Pro and Ala (aa 136‑173), a DNA binding homeobox (aa 236‑295) and a Glu:Asp‑rich transactivation domain (aa 305‑337). Over aa 1‑120, human NKX6.1 shares 96% aa identity with mouse NKX6.1.
