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 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 CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. 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).

- 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.
- Researchers should determine the optimal concentration of this reagent for their individual applications.
- 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.

The Ba13 monoclonal antibody specifically recognizes Cell surface glycoprotein CD200 receptor 3 (CD200R3) which is also known as CD200 cell surface glycoprotein receptor-like b (CD200RLb), CD200 receptor-like 3, and OX-2 Receptor 3. CD200R3 is a single-pass type I transmembrane glycoprotein that is encoded by Cd200r3 (CD200 receptor 3) which belongs to the immunoglobulin superfamily (IgSF). It is expressed on basophils and mast cells that are involved in protective immune responses against parasitic infections and in the development of allergic reactions. Cell surface CD200R3 presents as a disulfide-linked dimeric CD200R-like receptor. The cytoplasmic tail region of CD200R3 contains a positively charged lysine residue which allows this receptor to associate and signal through adaptor proteins such as DAP10, DAP12, CD3z, or FcRγ. CD200R3 functions as an activating receptor to regulate IgE-independent immune responses.
The antibody was conjugated to BD Horizon™ BV786 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 786-nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60-nm filter).
