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.

- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.

The LY9.7.144 monoclonal antibody specifically recognizes CD229 which is also known as SLAM family member 3 (SLAMF3), Lymphocyte antigen 9 (Ly-9), Lgp100, and T100. CD229 is a ~90-120 kDa type I transmembrane glycoprotein that is encoded by Ly9 (lymphocyte antigen 9) which belongs to the Signaling Lymphocytic Activation Molecule (SLAM) family within the immunoglobulin gene superfamily. The extracellular domain of CD229 contains four extracellular Ig-like domains (2 V-set and 2 C-set) extending in order from the N-terminus as V-C2-V-C2. The intracellular region of CD229 contains two ITSMs (immunoreceptor tyrosine-based switch motifs) and serves as a docking site for SH2-binding phosphatases and adapter molecules including SAP and EAT-2. CD229 is variably expressed on most thymocytes, T cells, NKT cells, B cells, NK cells, hematopoietic stem cells and progenitor cells, and monocytes. CD229 participates in homophilic adhesion interactions between these cells and in the regulation of their activation.
The antibody was conjugated to BD Horizon™ BUV563 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 which has an Ex Max of 348 nm and an acceptor dye. The tandem has an Em Max at 563 nm. BD Horizon BUV563 can be excited by the 355 nm ultraviolet laser. On instruments with a 561 nm Yellow-Green laser, the recommended bandpass filter is 585/15 nm with a 535 nm long pass to minimize laser light leakage. When BD Horizon BUV563 is used with an instrument that does not have a 561 nm laser, a 560/40 nm filter with a 535 nm long pass may be more optimal. Due to the excitation and emission characteristics of the acceptor dye, there may be spillover into the PE and PE-CF594 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
