Protogenin Antibody [Unconjugated]

Protogenin was detected in immersion fixed paraffin-embedded sections of human stomach tumor using Sheep Anti-Human Protogenin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6795) at 3 µg/ml overnight at 4 °C. 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 the HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016) and counterstained with hematoxylin (blue). Specific staining was localized to the membrane.

Protogenin was detected in immersion fixed frozen sections of mouse embryo (E9.5) using Sheep Anti-Human Protogenin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6795) at 10 µg/mL overnight at 4 °C. Tissue was stained using the NorthernLights™ 493-conjugated Anti-Sheep IgG Secondary Antibody (green; Catalog # NL012) and counterstained with DAPI (blue). Specific staining was localized to nuclei in the neural tube. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Background

PRTG (Protogenin; also Protein Shen-Dan) is a 175-180 kDa transmembrane (TM) member of the DEAL (DCC et al) family of proteins. It is expressed in the embryo in the period before E10.5 in mouse (day 28 in human), and appears in a widespread distribution. Through homophilic intercellular interaction, it regulates initial epiblast cell migration/ingression, thus impacting somite organization. Via its actions as a neural tube epithelial cell receptor, it binds soluble 60 kDa ERdj3, resulting in a suppression of neuron differentiation. Mature human PRTG is an 1115 amino acid (aa) type I TM glycoprotein. It contains a 917 aa extracellular domain (ECD) (aa 36‑952) and a 180 aa cytoplasmic region. The ECD possesses four consecutive Ig-like domains (aa 36‑411) followed by five FN type III domains (aa 419-914). There is one potential splice variant that shows a 49 aa substitution for Ala325 coupled to a deletion of aa 516-541. The ECD of human PRTG shares 93% aa identity with the ECD of mouse PRTG.
