Aqueous buffered solution containing ≤0.09% sodium azide.

Preparation And Storage

Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with BD Horizon BV510 under optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) 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).

Product Notices

  1. This antibody was developed for use in flow cytometry.
  2. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  7. Please refer to for technical protocols.
  8. BD Horizon Brilliant Stain Buffer is covered by one or more of the following US patents: 8,110,673; 8,158,444; 8,575,303; 8,354,239.
  9. BD Horizon Brilliant Violet 510 is covered by one or more of the following US patents: 8,575,303; 8,354,239.

The 232-5 monoclonal antibody specifically recognizes Butyrophilin 3 (BTN3), which is also known as CD277. BTN3 is comprised of three structurally related members, BTN3A1, BTN3A2, and BTN3A3. BTN3 molecules are transmembrane type 1 glycoproteins that belong to the Ig superfamily. The 232-5 antibody recognizes the variable region of the extracellular domains of BTN3 molecules. BTN3 molecules are differentially expressed by T, NKT, B, and NK cells, monocytes, macrophages, dendritic cells, as well as some stem cells and tumor cells. BTN3 expression is decreased upon lymphocyte activation. The extracellular domain of CD277 is structurally related to the B7 family of proteins that regulate T cell activation. A soluble form of the 232-5 antibody can serve as an agonist in BTN3-mediated regulation of anti-CD3 ± anti-CD28 antibody activated CD4+ or CD8+ T cells.

The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.

The BD Horizon Brilliant Violet™ 510 (BV510) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye with an excitation maximum (Ex Max) at 327-nm / 405-nm and an emission maximum (Em Max) at 512-nm. BV510, driven by BD innovation, is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 510-nm (e.g., a 525/50 bandpass filter). The dye can be excited by the UV (355-nm) laser resulting in cross-laser excitation and spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
