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

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

In a functional ELISA, Recombinant Human VISTA/B7-H5/PD-1H Fc Chimera (Catalog # 7126-B7) binds to immobilized Recombinant Human VSIG3 Fc Chimera (Catalog # 9229-VS) coated at 2 µg/mL (100 µL/well) in a dose-dependent manner (orange line). Binding is blocked (green line) by increasing concentrations of Mouse Anti-Human VISTA/B7-H5/PD-1H Monoclonal Antibody (Catalog # MAB71265). At 25 µg/mL, this antibody will block >90% of the binding.

Application
Recommended Usage

Blockade of Receptor-ligand Interaction

In a functional ELISA, 2-12 µg/mL of this antibody will block 50% of the binding of 5 μg/mL of Recombinant Human VISTA/B7-H5/PD-1H Fc Chimera (Catalog # 7126-B7) to immobilized Recombinant Human VSIG3 Fc Chimera (Catalog # 9229-VS) coated at 2 µg/mL (100 µL/well). At 25 µg/mL, this antibody will block >90% of the binding.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: VISTA/B7-H5/PD-1H

Platelet Receptor Gi24, also known as VISTA (V-domain Ig suppressor of T cell activation), B7-H5, B7H5, Dies1 (Differentiation of ESC-1), SISP1 and C10orf54, is a 55-65 kDa member of the Ig superfamily. It is a transmembrane molecule expressed in bone, on embryonic stem cells (ESCs), and on tumor cell surfaces. On ESCs, Gi24 appears to positively interact with BMP-4, potentiating BMP signaling and the transition from an undifferentiated to a differentiated state. On tumor cells, Gi24 both promotes MT1-MMP expression and activity and serves as a substrate for MT1-MMP. This increases the potential for cell motility. Mature human Gi24 contains a 162 aa extracellular region with one V-type Ig-like domain and a 96 aa cytoplasmic domain. Human Gi24 undergoes proteolytic cleavage by MT1-MMP, generating a soluble 30 kDa extracellular fragment plus a 25-30 kDa membrane-bound fragment. Over aa 33-194, human Gi24 shares 70% and 67% aa identity with mouse and rat Gi24, respectively.
