      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. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
      2. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
      3. For U.S. patents that may apply, see bd.com/patents.
      4. 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.
      5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      6. 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.
      7. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.
      8. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      9. An isotype control should be used at the same concentration as the antibody of interest.

      11. 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.

      B3506B4

      The B3506B4 monoclonal antibody specifically recognizes the Fc region of the human Immunoglobulin A (IgA) subclass known as IgA1. IgA1 is comprised of two identical heavy chains encoded by IGHA1, and two light chains, either Igκ or Igλ, that are linked together by disulfide bonds. The B3506B4 antibody does not crossreact with other human immunoglobulin heavy chain (IgH) subclasses, including the IgA2 subclass. IgA1 is expressed by plasmablasts, plasma cells, and memory B cells as well as by some myeloma or plasmacytoma cells. IgA1 is expressed in either a transmembrane form that serves as an antigen-specific B cell surface receptor or in a soluble secreted form. Monomeric and dimeric forms of IgA1 are found in the serum although the monomeric form predominates. Multimeric forms of IgA1 connected by a J-chain and secretory component are also found in bodily secretions. Secretory IgA is transported across epithelial cells and secreted into the lumen of mucosal tissues including the gastrointestinal and respiratory tracts and is found in human breast milk. IgA1 functions in the agglutination of microbes and can block their adherence to or infection of human cells. It can also bind to CD89 (FcαRI) expressed on neutrophils, monocytes, macrophages, and eosinophils to trigger a variety of immune responses including phagocytosis, antibody-dependent cell-mediated cytotoxicity, and the release of inflammatory cytokines and mediators such as in the response to microbes.

      RY610
      The BD Horizon RealYellow™ 610 (RY610) Dye is part of the BD® family of yellow-green dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 557-nm and an emission maximum (Em Max) at 610-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RY610 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), RY610 can be used as an alternative to PE-CF594 and we recommend using an optical filter centered near 610-nm (eg, a 610/20-nm bandpass filter). For spectral instruments equipped with a Yellow-Green laser (561-nm), it can be used in conjunction with PE-CF594.
