Scientific Data

Western Blot Detection of Human Neurogenin‑3 antibody by Western Blot. View Larger

Detection of Human Neurogenin‑3 by Western Blot. Western blot shows lysates of human placenta and prostate tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Neurogenin-3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3444) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Neurogenin-3 at approximately 25 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Immunohistochemistry View Larger

Neurogenin‑3 in Human Placenta. Neurogenin‑3 was detected in immersion fixed paraffin-embedded sections of human placenta using Sheep Anti-Human Neurogenin‑3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3444) at 1 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Sheep IgG VisUCyte™ HRP Polymer Antibody (VC006). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm and cell nuclei in decidual cells. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Background: Neurogenin-3

Neurogenin-3 (NGN3; also Protein atonal homolog 5) is a 23 kDa, developmentally expressed nuclear protein that belongs to a family of atonal-related basic helix‑loop‑helix (bHLH) transcription factors. bHLH proteins typically form dimers when binding to DNA. NGN3 expression is required for the lineage differentiation of all endocrine cell types in the pancreas, including the formation of islet beta  cells. NGN3 is also neurogenic, controlling the number of dendrites generated by hippocampal neurons. Human NGN3 is 214 amino acids (aa) in length. It contains a DNA binding region (aa 84‑95) plus an HLH motif (aa 96‑136). Over aa 3‑214, human NGN3 shares 76% and 84% aa identity with mouse and canine NGN3, respectively.
