BD Horizon™ BV421 Mouse Anti-Human VISTA
Clone MIH65.rMAb (also known as MIH65) (RUO)
Multiparameter flow cytometric analysis of VISTA expression on human peripheral blood leucocyte populations. Human whole blood was stained with either BD Horizon BV421™ Mouse IgG1, κ Isotype Control (Cat. No. 562438; Left Plot) or BD Horizon BV421 Mouse Anti-Human VISTA antibody (Cat. No. 566750/566751; Right Plot). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899).Two-parameter flow cytometric contour plots showing the correlated expression of VISTA (or Ig Isotype control staining) versus side light-scatter (SSC-A) signals were derived from gated events with the forward and side light-scatter characteristics of viable leucocyte populations. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software.

Preparation And Storage
Recommended Assay Procedures
BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome-conjugated antibodies are bound to CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

The MIH65.rMAb is a recombinant monoclonal antibody derived from MIH65 hybridoma cells. MIH65.rMAb specifically binds to human V-domain Ig suppressor of T cell activation (VISTA) like the conventional MIH65 antibody and performs like the MIH65 antibody when used to stain cells and analyze them by flow cytometry. VISTA is also known as B7-H5 (B7H5), PD-1H, DD1alpha (DD1α), chromosome 10 open reading frame 54 (C10orf54), Platelet Receptor Gi24 (GI24), or Stress induced secreted protein 1 (SISP1). VISTA is a 55-65 kDa single-pass, type I transmembrane glycoprotein that is encoded by VSIR (V-set immunoregulatory receptor) which belongs to the V-set domain containing family within the Ig superfamily. VISTA is primarily expressed on precursors and mature cells of the hematopoietic lineage including, monocytes, macrophages, neutrophils, dendritic cells (DC), T cells, regulatory T cells (Treg), and natural killer (NK) cells but not B cells. VISTA functions as an inhibitory regulator that can suppress T cell proliferation and cytokine production.
The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max near 407 nm and Em Max near 421 nm, BD Horizon BV421 can be excited by the violet laser (405 nm) and detected with a 450/50 nm filter. BD Horizon BV421 conjugates are very bright, often exhibiting a 10-fold improvement in brightness compared to Pacific Blue™ conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue, and BD Horizon V450 cannot be used simultaneously.
