    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.

    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

    1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
    2. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
    3. An isotype control should be used at the same concentration as the antibody of interest.
    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. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
    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. Researchers should determine the optimal concentration of this reagent for their individual applications.
    8. BD Horizon Brilliant Violet 421 is covered by one or more of the following US patents: 8,158,444; 8,362,193; 8,575,303; 8,354,239.
    9. BD Horizon Brilliant Stain Buffer is covered by one or more of the following US patents: 8,110,673; 8,158,444; 8,575,303; 8,354,239.

    12. 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.

    AER-37

    The AER-37 (CRA-1) monoclonal antibody specifically recognizes FcεRIα which is also known as the high affinity immunoglobulin epsilon receptor subunit alpha (Fc-epsilon RI-alpha). FcεRIα is a type I transmembrane glycoprotein that is encoded by FCER1A (Fc fragment of IgE receptor Ia) which belongs to the Ig gene superfamily. FcεRIα serves as the binding subunit for the Fc region of IgE. It forms part of a heterotetrameric, high-affinity IgE Fc receptor (FceR1/FcεR1) that includes signal transducing subunits, one β-chain (FcεRIβ encoded by MS4A2) and two disulfide-linked γ-subunits (FcεRIγ encoded by FCER1G).  FcεRIα is normally expressed on basophils and mast cells and can also be expressed on some monocytes, Langerhans cells, dendritic cells, and eosinophils from allergic donors. FcεRIα plays a major role in allergic responses and in the presentation of allergens to the immune system. The AER-37 antibody reportedly does not compete with IgE for FceR1 binding.

    BV421
    The BD Horizon Brilliant Violet™ 421 (BV421) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye has an excitation maximum (Ex Max) of 407-nm and an emission maximum (Em Max) at 423-nm. Driven by BD innovation, BV421 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 420-nm (e.g., a 431/28-nm or 450/50-nm bandpass filter). BV421 is an ideal alternative for V450 as it is approximately ten times brighter with less spillover into the BV510/V500 detector. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
