Scientific Data Images for Human VISTA/B7-H5/PD-1H Antibody

Detection of Human VISTA/B7-H5/PD-1H antibody by Western Blot.

Detection of Human VISTA/B7-H5/PD-1H by Western Blot.

Western blot shows lysates of human placenta tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human VISTA/B7-H5/PD-1H Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7126) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for VISTA/B7-H5/PD-1H at approximately 45-65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of VISTA/B7-H5/PD-1H antibody in Human PBMCs antibody by Flow Cytometry.

Detection of VISTA/B7-H5/PD-1H in Human PBMCs by Flow Cytometry.

Human peripheral blood mononuclear cells (PBMCs) were stained with Mouse Anti-Human CD11b/Integrin alpha M APC-conjugated Monoclonal Antibody (Catalog # FAB16991A) and either (A) Sheep Anti-Human VISTA/B7-H5/PD-1H Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7126) or (B) Normal Sheep IgG Control (Catalog # 5-001-A) followed by Phycoerythrin-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # F0126).

Human VISTA/B7-H5/PD-1H Antibody in ELISA Standard Curve.

Human VISTA/B7-H5/PD-1H ELISA Standard Curve.

Recombinant Human VISTA/B7-H5/PD-1H protein was serially diluted 2-fold and captured by Mouse Anti-Human VISTA/B7-H5/PD-1H Monoclonal Antibody (Catalog # MAB71264) coated on a Clear Polystyrene Microplate (Catalog # DY990). Sheep Anti-Human VISTA/B7-H5/PD-1H Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7126) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Applications for Human VISTA/B7-H5/PD-1H Antibody

Application
Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human VISTA/B7-H5/PD-1H Monoclonal Antibody (Catalog # MAB71264).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human VISTA/B7-H5/PD-1H DuoSet ELISA Kit (Catalog # DY7126-05) for convenient development of a sandwich ELISA.

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, VISTA appears to positively interact with BMP-4, potentiating BMP signaling and the transition from an undifferentiated to a differentiated state. On tumor cells, VISTA both promotes MT1-MMP expression and activity and serves as a substrate for MT1-MMP. This increases the potential for cell motility. Mature human VISTA contains a 162 aa extracellular region with one V-type Ig-like domain and a 96 aa cytoplasmic domain. Human VISTA 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 VISTA shares 70% and 67% aa identity with mouse and rat Gi24, respectively.
