Preparation And Storage
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).

- 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.
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.

The 5B5 monoclonal antibody specifically binds to human CD77, a small neutral glycosphingolipid also referred to as globotriaosylceramide (Gb3), Burkitt 's lymphoma associated antigen (BLA), ceramide trihexoside (CTH), and Pk blood group antigen. CD77 is expressed on a subset of germinal center B-lymphocytes including centroblasts that are found with greater frequency in tonsil and mucosal lymphoid tissues and less frequently in peripheral blood, bone marrow and spleen. It has been described as a receptor for Shiga Toxin, produced by Shigella dysenteriae, and Verotoxin 1 (VT1), produced by some strains of E. coli. CD19 has been reported as a ligand for CD77. This interaction may function in adhesion and signal transduction at a specific stage of B cell differentiation. Studies have shown that cross-linking CD77 induces apoptosis in some B cell lines.
