Scientific Data Images for Human VSIG1 Antibody
Detection of Human VSIG1 by Western Blot.
Western blot shows lysates of human stomach tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human VSIG1 Monoclonal Antibody (Catalog # MAB4818) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for VSIG1 at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
VSIG1 in Human Testis.
VSIG1 was detected in immersion fixed paraffin-embedded sections of human testis using Mouse Anti-Human VSIG1 Monoclonal Antibody (Catalog # MAB4818) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membranes in spermatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
Detection of Human VSIG1 by Simple WesternTM.
Simple Western lane view shows lysates of human stomach tissue, loaded at 0.5 mg/mL. A specific band was detected for VSIG1 at approximately 48 kDa (as indicated) using 100 µg/mL of Mouse Anti-Human VSIG1 Monoclonal Antibody (Catalog # MAB4818). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.Applications for Human VSIG1 Antibody

Background: VSIG1
VSIG1 (V-set and Ig domain-containing protein 1; also Glycoprotein A34) is a variably glycosylated 55‑70 kDa member of the JAM family of proteins. It has restricted expression, being limited to testicular germ cells plus pancreatic duct and gastric epithelium. VSIG1 is likely to serve as an adhesion molecule. Mature human VSIG1 is 366 amino acids (aa) in length. It is a type I transmembrane glycoprotein that contains a 211 aa extracellular domain (ECD). The ECD contains one V-type (aa 22‑132) and one C2-type Ig-like domain (aa 140‑227). Over aa 22‑234, human VSIG1 is 83% aa identical to both mouse and canine VSIG1. At least one potential splice variant exists in human. It shows an insertion of 36 aa after Ser72 and a deletion of aa 133‑387.
