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).
Product Notices
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- 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.

Companion Products
The IPI683.rMAb recombinant monoclonal antibody specifically recognizes Programmed cell death 1 ligand 2 (PD-L2) which is also known as CD273 and Butyrophilin B7-DC (B7-DC). This regulatory molecule is a 42-kDa type I membrane glycoprotein encoded by PDCD1LG2 which belongs to the B7 family of the Ig superfamily. CD273 (PD-L2) is comprised of an extracellular region with an N-terminal IgV-like domain followed by an IgC2-type domain, a transmembrane sequence, and a cytoplasmic tail. Although not detected on resting leucocytes, its expression is upregulated upon activation of macrophages and dendritic cells (DC) by a variety of stimulatory factors including IL-4, IL-13, or GM-CSF. CD273 (PD-L2) has been recognized as an inhibitory regulator of human T-cell activation and serves as a ligand for the coinhibitory receptor, CD279 (PD-1), a receptor that likewise binds to the CD274 (PD-L1) ligand. CD273 (PD-L2) also binds to Repulsive guidance molecule b (RGMb) that is expressed by T cells, macrophages, neutrophils, and DC. RGMb may associate with other receptors that transduce costimulatory or coinhibitory signals.
