      Preparation And Storage

      Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.

      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

      1. Researchers should determine the optimal concentration of this reagent for their individual applications.
      2. 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.
      3. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      4. An isotype control should be used at the same concentration as the antibody of interest.
      5. 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.

      7. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
      8. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      9. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      10. 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.

      BM16

      The BM16 monoclonal antibody specifically binds to CD294. CD294 is encoded by PTGDR2 (Prostaglandin D2 receptor 2) and is also known as CRTH2 (chemoattractant receptor-homologous molecule expressed on Th2 cells), GPR44 (G protein-coupled receptor 44), DL1R, and DP2. CD294 is a member of the G protein-coupled leukocyte chemoattractant receptor family. CD294 is expressed on Th2 cells and type-2 innate lymphoid cells (ILC2), but not Th1 type cells. CD294 is detectable on CD4+ T cells in fresh PBMC but not on B cells and NK cells. CD294 is also expressed on peripheral blood basophils and eosinophils, suggesting its involvement allergic reactions. Phenotypic analysis of CD4+ T cells expressing CRTH2 demonstrated that they were also CD45RA-negative and CD45RO+ and CD25+. These cells produce Th2- but little or no Th1-type cytokines upon stimulation with PMA and Ionomycin.

      RY586
      The BD Horizon RealYellow™ 586 (RY586) Dye is part of the BD family of yellow-green dyes. It is a small organic fluorochrome with an excitation maximum (Ex Max) at 565-nm and an emission maximum (Em Max) at 586-nm. Driven by BD innovation, RY586 can be used on both spectral and conventional cytometers and is designed to be excited by the Yellow-Green laser (561-nm) with minimal excitation by the 488-nm Blue laser. For conventional instruments equipped with a Yellow-Green laser (561-nm), RY586 can be used as an alternative to PE and we recommend using an optical filter centered near 586-nm (eg, a 586/15-nm bandpass filter). For spectral instruments equipped with a Yellow-Green laser (561-nm), it can be used in conjunction with PE. Compared to PE, RY586 is similar in brightness, minimal spillover into Blue detectors, and increased spillover into the 610/20-nm (PE-CF594) detector. Please ensure that your instrument configuration (lasers and optical filters) is appropriate for this dye.
