Detects human Neurogenin-3 in direct ELISAs and Western blots. In direct ELISAs, approximately 10% cross-reactivity with recombinant mouse Neurogenin-3 is observed, and less than 1% cross-reactivity with recombinant human Neurogenin-1 is observed.
Polyclonal Sheep IgG
E. coli-derived recombinant human Neurogenin-3 Met1-Leu214 Accession # Q9Y4Z2
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
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.

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.
