Any use of products other than the permitted use without the express written authorization of Becton, Dickinson and Company is strictly prohibited.
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.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
- Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.

Companion Products
The 1-1-2 monoclonal antibody specifically recognizes the Qa-2 MHC class Ib antigen, which is expressed at higher levels on mature T lymphocytes than on B cells. Its expression is upregulated in the late stages of T-cell maturation. Qa-2 is a 40 kDa GPI-linked cell surface molecule encoded by the Q5, Q6, Q7, and/or Q9 genes of the H-2 complex. A 39 kDa soluble form results from alternative splicing of the transcript. Although Qa-2 is nonpolymorphic, its level of expression on both T and B lymphocytes varies among inbred mouse strains. High expressors include strains carrying the H-2[b] haplotype low expressors include H-2[d] strains, and H-2[k] strains are Qa-2-negative.
The antibody was conjugated to BD Horizon™ BV750 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 750-nm. BD Horizon Brilliant BV750 can be excited by the violet laser (405 nm) and detected with a 750/30 nm filter with a 740 nm long pass. Due to spectral differences between labeled cells and beads, using BD™ CompBeads can result in incorrect spillover values when used with BD Horizon BV750 reagents. Therefore, the use of BD CompBeads or BD CompBeads Plus to determine spillover values for these reagents is not recommended.
