Protogenin in Embryonic Mouse Neural Tube. Protogenin was detected in immersion fixed frozen sections of embryonic mouse neural tube (E9) using 10 µg/mL Sheep Anti-Mouse Protogenin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4919) overnight at 4 °C. Tissue was stained with the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; NL010) and counterstained with DAPI (blue).

Protogenin in Mouse Neural Tube. Protogenin was detected in immersion fixed frozen sections of mouse neural tube (E9.5) using Sheep Anti-Mouse Protogenin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4919) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (yellow; NL010) and counterstained with DAPI (blue).

Detection of Protogenin in Mouse Embryo. Protogenin was detected in immersion fixed paraffin-embedded 13.5 d.p.c sections of Mouse Embryo using Sheep Anti-Mouse Protogenin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4919) at 10 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Sheep IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC006). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm and cell membranes in neuronal cells.

Protogenin (Early/proto in expression, neogenin-like; also Prtg) is a 130 kDa (predicted), type I transmembrane member of the DCC/Neogenin family of proteins. It is expressed in mouse presomitic mesoderm, paraxial mesoderm, and neural tube. Mature mouse protogenin is 1168 amino acids (aa) in length. It contains a 920 aa extracellular domain (ECD) (aa 24-943) plus a 224 aa cytoplasmic region. The ECD contains four consecutive Ig-like domains (aa 24-405), followed by five sequential fibronectin type III domains (aa 413-908). The ECD of mouse protogenin shares 98%, 87%, and 93% aa sequence identity with the ECD of rat, chick, and human protogenin, respectively.
