Preparation And Storage
Recommended Assay Procedures
For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) 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).
Product Notices
- This antibody was developed for use in flow cytometry.
- 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.

CD21 is a 145 kDa transmembrane glycoprotein that is expressed on mature B cells, follicular dendritic cells, a subset of immature thymocytes and on some epithelial cells. CD21 is also known as the C3d Receptor, Complement Receptor 2 (CR2), and the Epstein-Barr Virus receptor, (EBV-R). CD21 is part of a large signal-transduction complex that also includes CD19, CD81 and Leu13. CR2 serves as a receptor for the activation fragments of complement component C3, i.e. C3d, iC3d, and C3dg and C3d-bound antigens and plays a central role in the immune response by amplifying B-cell activation and proliferation. CR2 is also the receptor for EBV by binding its surface glycoprotein gp350/220. Anti-human CR2 hybridomas were generated from Cr2-/-mice (lacking the cr2 gene, that encodes CR2 and CR1 in mice) immunized with the recombinant protein representing the first two amino-terminal short consensus repeats (SRC) of human CR2, SCR1-2. Both the C3d and EBV binding sites of hu CR2 were localized to these sites. Clone 1048 has been reported to specifically react with CR2-expressing cells and to inhibit CR2 interactions with C3 fragments or the EBV surface protein, gp350/220.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
