HEK293 human embryonic kidney cell line transfected with either (A) human VSIG3 or (B) irrelevant protein, and eGFP, was stained with Mouse anti-Human VSIG3 monoclonal antibody (Catalog # MAB92293) followed by Allophycocyanin-conjugated anti-Mouse IgG Secondary Antibody (F0101B). Quadrant markers were set based on isotype control antibody staining (MAB0041, data not shown). Staining was performed using our Staining Membrane-Associated Proteins protocol.

VSIG3 Binding to VISTA/B7-H5/PD-1H by Human VISG3 Antibody.

In a functional ELISA, 0.2-2 µg/mL of Mouse Anti-Human VSIG3 Monoclonal Antibody (Catalog # MAB92293) will block 50% of the binding of 1 µg/mL of Recombinant Human VSIG3 Fc Chimera (9229-VS) to immobilized Recombinant Human VISTA/B7-H5/PD-1H Fc Chimera (7126-B7) coated at 1 µg/mL (100 µL/well). At 10 µg/mL, this antibody will block >90% of the binding.

Background: VSIG3

VSIG3 (V-set and Ig domain-containing protein 3; also BT-IgSF and IGSF11) is a 52 kDa brain and testis-specific protein that belongs to the IGSF11 family of proteins. It is expressed by neurons, astrocytes and oligodendroglia. VSIG3 is an adhesion molecule that forms Ca-independent homophilic interactions in trans. Human VSIG3 is 413 amino acids (aa) in length. It is a type I transmembrane glycoprotein that contains a 219 aa extracellular domain (ECD). The ECD contains one V-type (aa 23‑136) and one C2-type Ig-like domain (aa 144‑234). Over aa 23‑245, human VSIG3 is 94% aa identical to mouse VSIG3. Two potential splice variants exist in human. Both exhibit a 16 aa substitution for the first 17 aa of the signal sequence, and one contains an additional single Ala substitution for aa 211‑235.
