Scientific Data Images for Human VSIG2 Antibody

Detection of VSIG2 antibody in HEK293 Human Cell Line Transfected with Human VSIG2 and eGFP antibody by Flow Cytometry.

Detection of VSIG2 in HEK293 Human Cell Line Transfected with Human VSIG2 and eGFP by Flow Cytometry.

HEK293 human embryonic kidney cell line transfected with (A) human VSIG2 or (B) irrelevant transfectants and eGFP was stained with Mouse Anti-Human VSIG2 Monoclonal Antibody (Catalog # MAB51771) followed by APC-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). Quadrant markers were set based on control antibody staining (Catalog # MAB002). View our protocol for Staining Membrane-associated Proteins.

Background: VSIG2

V-set and immunoglobulin domain-containing protein 2 (VSIG2), also known as cortical thymocyte-like protein (CT-like protein), is a member of the immunoglobulin superfamily (Igsf) that was originally described in Xenopus and was referred to as cortical thymocyte marker in Xenopus, or CTX. The clone isolated from the human genomic library was called CTH (1). Mature human VSIG2 is a single-pass type I transmembrane protein with a 220 amino acid (aa) extracellular domain (ECD) that contains one C2-type and one V-type immunoglobulin-like domains, and a 63 aa cytoplasmic region linked to the ECD by a short 21 aa transmembrane domain. Human VSIG2 ECD shares 85% and 86% aa sequence identity with mouse and rat VSIG2, respectively. VSIG2 is structurally related to the B7 family of immune regulatory proteins. Our studies at R&D Systems show that VSIG2 inhibits T cell activation, including IL17 and interferon gamma production.
