Preparation And Storage
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
- 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.

The 4G2 monoclonal antibody specifically recognizes CD319 which is also known as CD2-like receptor activating cytotoxic cells (CRACC), Signaling lymphocytic activation molecule 7 (Slamf7), or novel Ly9. CD319 (CRACC) is a single-pass type I transmembrane glycoprotein that is encoded by Slamf7 (SLAM family member 7) which belongs to the SLAM family within the CD2-subset of the immunoglobulin superfamily (IgSF) of cell surface receptors. This receptor is comprised of an extracellular region with one N-terminal Ig-like V-type (IgV) domain followed by one Ig-like C2-type (IgC2) domain. Its cytoplasmic tail contains two immunoreceptor tyrosine-based switch motifs (ITSMs). This receptor is variably expressed on activated CD4+ T cells and CD8+ T cells, NKT cells, NK cells, B cells, monocytes, macrophages, and dendritic cells. CD319 (CRACC) serves as a homotypic adhesion molecule that can self-associate and trigger cellular activation, such as cell-mediated cytotoxicity, when its cytoplasmic domains are associated with adaptor molecules including EWS-activated transcript 2 (EAT-2) and possibly EAT-2-related transducer (ERT). In cells that lack EAT-2, CD319 (CRACC) may exhibit an inhibitory function.
The antibody was conjugated to BD Horizon™ BV711 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 711-nm. BD Horizon BV711 can be excited by the violet laser and detected in a filter used to detect Cy™5.5 / Alexa Fluor® 700-like dyes (eg, 712/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there may be moderate spillover into the Alexa Fluor® 700 and PerCP-Cy5.5 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
