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).
For optimal results, it is recommended to perform 2 washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescence staining, prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.

The 24F.10C12 monoclonal antibody specifically recognizes Programmed Death Ligand 2 (PD-L2, PDL2) which is also known as CD273, and B7-DC (B7DC). PD-L2 (CD273) is a type 1 transmembrane glycoprotein that is encoded by PDCD1LG2 (programmed cell death 1 ligand 2) which belongs to the B7 family within the Ig superfamily. PD-L2 (CD273) serves as a ligand for CD279, the Programmed Death 1 (PD-1) receptor. CD273 is expressed on dendritic cells, activated monocytes, medullary thymic epithelial cells, placental trophoblasts, and myocardial endothelium. PD-L2 (CD273) can function as a coinhibitor of T cell functions by binding to and signaling through CD279 (PD-1). PD-L2 (CD273) can also reportedly act through another receptor to costimulate T cell activation and cytokine production. The 24F.10C12 antibody can reportedly block the binding of PD-L2 (CD273) to CD279 (PD-1).
