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.
Product Notices
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
- 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.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- 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 MIH1 monoclonal antibody specifically binds to CD274, which is also known as, B7 homolog 1 (B7-H1), Programmed cell death 1 ligand 1 (PDCD1 ligand, PDCD1L1, PDCD1LG1), or Programmed death ligand 1 (PD-L1, PDL1). CD274 and PD-L2 (CD273) are type I transmembrane glycoproteins that belong to the B7 family and serve as ligands for CD279 (Program Death 1/PD-1). CD274 is expressed on antigen-presenting cells including activated monocytes/macrophages and dendritic cells, as well as, activated T cells, and keratinocytes. CD274 is also expressed on placental trophoblasts, myocardial endothelium, cortical thymic epithelial cells, and on most carcinomas. CD274 plays an important role in regulating T cell responses. The MIH1 antibody blocks CD279 binding to CD274 and can enhance the proliferation and cytokine production of activated T cells.
