Regulatory Status Legend
The 11-5 monoclonal antibody specifically recognizes MHC class I-restricted T cell-associated molecule (CRTAM) that is also known as CD355 or Cytotoxic and regulatory T-cell molecule. CD355 (CRTAM) is encoded by Crtam which belongs to the Nectin family of cell adhesion molecules within the immunoglobulin superfamily. This type I transmembrane glycoprotein contains a V-type Ig domain, followed by a C-type Ig domain, a transmembrane region, and an intracellular region that contains a PDZ-binding motif at the C terminus. CD355 (CRTAM) is transiently expressed as a homodimer on activated NK cells, NKT cells, γδ T cells, CD8+ T cells, or CD4+ T cells. Through its V-type Ig domain, CRTAM (CD355) binds to Nectin-like molecule 2 (Necl-2) and plays important roles in adhesive interactions between different cell types and in cellular migration.
The antibody was conjugated to BD Horizon™ BUV737 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348-nm and an acceptor dye with an Em Max at 737-nm. BD Horizon Brilliant BUV737 can be excited by the ultraviolet laser (355 nm) and detected with a 740/35 filter. Due to the excitation of the acceptor dye by other laser lines, there may be significant spillover into channels detecting Alexa Fluor® 700-like dyes (eg, 712/20-nm filter).
Due to spectral differences between labeled cells and beads, using BD™ CompBeads can result in incorrect spillover values when used with BD Horizon BUV737 reagents. Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended. Different BUV737 reagents (eg, CD4 vs. CD45) can have slightly different fluorescence spillover therefore, it may also be necessary to use clone specific compensation controls when using these reagents.
BUV737 is a tandem fluorochrome that combines BD Horizon BUV395 and an acceptor dye with an Em Max at 737 nm. Due to the excitation of the acceptor dye by other laser lines, there may be significant spillover in to channels detecting Alexa Fluor® 700 like dyes (for example, 712/20-nm filter). BUV737 has been exclusively developed by BD Biosciences for instruments equipped with a 355-nm UV laser.

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 BUV737 under optimal conditions that minimize unconjugated dye and antibody.
- This antibody was developed for use in flow cytometry.
- 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.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.

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).
