Preparation and Storage
推奨アッセイ手順
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.
