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 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 Ab93 monoclonal antibody (aka, Antibody93) specifically recognizes a common epitope on the extracellular domains of mouse CD16 (Fc gamma RIII/FcγRIII encoded by Fcgr3) and CD32 (Fc gamma RIIB/FcγRIIB encoded by Fcgr2b). Therefore, Ab93 is referred to as an Anti-CD16/32 or Anti-FcgRII/III antibody. CD16 is variably expressed on neutrophils, macrophages, and natural killer (NK) cells whereas CD32 is expressed on B cells, monocytes, granulocytes, platelets and endothelial cells. CD16 and CD32 serve as low affinity receptors for IgG Fc constant regions and are involved in regulating various cellular functions including antibody-dependent cellular toxicity (ADCC), phagocytosis, effector cell degranulation, and B cell proliferation. In addition to identifying CD16- or CD32-positive cells, the Ab93 antibody is useful in phenotyping studies for blocking nonspecific staining due to Fc receptor-mediated binding of other antibodies. Ab93 is also useful in functional studies due to its Fc receptor blocking capability or by its capacity to crosslink Fc receptors leading to signal transduction that triggers cellular responses. Ab93 (Rat IgG2a, λ) and clone 2.4G2 (Rat IgG2b, κ), another mouse CD16/32-specific antibody, reportedly have similar specificities. The differences in the Ig heavy chain or Ig light chain isotypes of these CD16/32-specific antibodies afford flexibility in the design of experimental model systems involving other antibodies.
