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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- BD Horizon Brilliant Ultraviolet 395 is covered by one or more of the following US patents: 8,158,444; 8,575,303; 8,354,239.

- Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

Companion Products
The IPI652.rMAb recombinant monoclonal antibody specifically recognizes Programmed cell death 1 ligand 1 (PDCD1 ligand 1, PDCD1L1, PDCD1LG1) which is also known as Programmed death ligand 1 (PD-L1 or PDL1) as well as CD274, or B7 homolog 1 (B7-H1, B7H1). PD-L1 (CD274) and PD-L2 (CD273) are type I transmembrane glycoproteins that belong to the B7 family within the Ig gene superfamily and serve as ligands for CD279 (Program Death 1/PD-1). PD-L1 (CD274) is expressed on antigen-presenting cells including activated monocytes, macrophages, and dendritic cells (DCs) as well as activated T cells, B cells, NK cells, and keratinocytes. PD-L1 (CD274) is also variably expressed on placental trophoblasts, myocardial endothelium, cortical thymic epithelial cells, and tumor cells. PD-L1-mediated signaling through PD-1 regulates T cell responses important for providing protective immunity while maintaining peripheral tolerance. This immune signaling checkpoint may also suppress antitumor immune responses and prevent tumor rejection.
