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 to the dye under optimum conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation).  When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells.   However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls.  It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385).

The 17B5 monoclonal antibody specifically recognizes CD137 which is also known as 4-1BB. CD137 (4-1BB) is an ~39 kDa single-pass type I transmembrane glycoprotein that is encoded by Tnfsf9 (Tnfsf9 tumor necrosis factor ligand superfamily, member 9). Monomeric and multimeric forms of CD137 (4-1BB) are expressed on thymocytes as well as activated T cells, B cells, NK cells, monocytes, macrophages, and dendritic cells (DC). It is also expressed on T regulatory cells and may function in their proliferation. CD137 (4-1BB) plays a costimulatory role in the interactions between T cells, B cells, and antigen presenting cells as it binds to 4-1BB ligand (4-1BBL), which is also known as CD137 ligand (CD137L). The 17B5 antibody can reportedly block these costimulatory interactions.

The BD Horizon Brilliant Violet™ 650 (BV650) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This tandem fluorochrome is comprised of a BV421 donor with an excitation maximum (Ex Max) of 406-nm and an acceptor dye with an emission maximum (Em Max) at 649-nm. BV650, driven by BD innovation, is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 650-nm (e.g., a 660/20-nm bandpass filter). The acceptor dye can be excited by the Red (628–640-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
