Biotinylated recombinant human VISTA-Avi (black circles) binds to immobilized recombinant human IGSF11/BT-IgSF/VSIG3-FC. Ultra-LEAF™ purified anti-human VISTA (PD-1H) (clone W20178L) (purple squares) inhibits the binding in a dose-dependent manner, whereas the Ultra-LEAF™ purified rat IgG2a, κ isotype control (Cat. No. 400544) (gray triangles) does not have the effect. This antibody blocks the binding of 5 µg/mL biotinylated recombinant human VISTA-Avi to 2 µg/mL immobilized recombinant human IGSF11/BT-IgSF /VSIG3-FC. ND50 range: 1-6 µg/mL.

VISTA, V-domain Ig suppressor of T cell activation, suppresses T cell activation and was initially identified by affymetrix analysis of activated versus resting mouse CD25+ CD4+ natural Treg cells. Human Vista is a type I transmembrane protein with a single extracellular IgV domain. It is 311 amino acids (aa) long, contains a 32-aa signal peptide, a 130-aa extracellular IgV domain, 33-aa stalk region, 20-aa transmembrane domain, and 96-aa cytoplasmic tail. VISTA shares significant sequence homology with the B7 family ligands PD-L1 and PD-L2. VISTA is predominantly expressed in hematopoietic tissues, highly expressed in human placenta, which may be indicative of a functional role for VISTA in allofetal tolerance. Flow cytometry shows that human VISTA is expressed in subsets of CD11bhi blood monocytes, dendritic cells, about 20% of CD4, with low density in CD8 T cells, and CD66b+ neutrophils at an intermediate intensity. VISTA serves both as a ligand (for antigen presenting cells) and as a receptor (for T cells). B7-H5 expressing on APCs or soluble B7-H5-Ig fusion proteins inhibit T cell proliferation and cytokine production in vitro. B7-H5 also inhibits the expression of T cell activation markers CD44 and CD69. In murine tumor models, anti-VISTA monoclonal antibodies (mAbs) prime to an increased number and elevated function of intratumoral T cells and in that way boost antitumor immunity. VISTA is negative checkpoint regulator and a promising target for cancer immunotherapy.

Related FAQs
- Do you guarantee that your antibodies are totally pathogen free?
-
BioLegend does not test for pathogens in-house aside from the GoInVivo™ product line. However, upon request, this can be tested on a custom basis with an outside, independent laboratory.
- Does BioLegend test each Ultra-LEAF™ antibody by functional assay?
-
No, BioLegend does not test Ultra-LEAF™ antibodies by functional assays unless otherwise indicated. Due to the possible complexities and variations of uses of biofunctional antibodies in different assays and because of the large product portfolio, BioLegend does not currently perform functional assays as a routine QC for the antibodies. However, we do provide references in which the antibodies were used for functional assays and we do perform QC to verify the specificity and quality of the antibody based on our strict specification criteria.
- Does BioLegend test each Ultra-LEAF™ antibody for potential pathogens?
-
No, BioLegend does not test for pathogens in-house unless otherwise indicated. However, we can recommend an outside vendor to perform this testing as needed.
- Have you tested this Ultra-LEAF™ antibody for in vivo or in vitro applications?
-
We don't test our antibodies for in vivo or in vitro applications unless otherwise indicated. Depending on the product, the TDS may describe literature supporting usage of a particular product for bioassay. It may be best to further consult the literature to find clone specific information.
