Regulatory Status Legend
The 7H22-E16 monoclonal antibody specifically binds to CD268, which is also known as, B cell-activating factor receptor (BAFF-R), or BAFF Receptor 3 (BR3). CD268 is a type III transmembrane protein that is likewise known as Tumor necrosis factor receptor superfamily member 13C (Tnfrsf13c). CD268/BAFF-R is a receptor for CD257 (also known as, BAFF, Blys, TALL-1, or THANK) and is expressed on B cells and a subset of activated/memory CD4+ T cells. B cells express two other BAFF receptors, CD267/TACI, or CD269/BCMA, at various times during their differentiation. CD268/BAFF-R expression starts at the transitional stage of B cell development and increases throughout B cell maturation. CD267/BAFF-R mediates most BAFF-dependent functions including B cell survival, the activation of B cell proliferation and immunoglobulin secretion, and the costimulation of T cells. Overexpression of BAFF in mice and humans is associated with autoimmunity, whereas CD268/BAFF-R deficiency may cause severe impairment in humoral responses.
The antibody was conjugated to BD Horizon™ BUV661 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 661-nm. BD Horizon Brilliant BUV661 can be excited by the ultraviolet laser (355 nm) and detected with a 670/25 filter and a 630 nm LP. Due to cross laser excitation of this dye, there may be significant spillover into channels detecting APC-like emissions (eg, 670/25-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 BUV661 reagents. Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended. Different BUV661 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.

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 BUV661 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).
