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.

The OX-41 monoclonal antibody specifically reacts with the rat signal-regulatory protein (SIRP). The rat SIRP (CD172) is a 110-120-kDa type 1 transmembrane protein with three extracellular immunoglobulin superfamily domains and two intracellular Immunoreceptor Tyrosinebased Inhibitory Motifs (ITIM). The SIRP ITIMs are phosphorylated in response to activation by growth hormone, epidermal growth factor, and integrin-mediated cell adhesion. The phosphorylated SIRP associates with tyrosine phosphatases SHP-1 and/or SHP-2. In the rat, SIRP is selectively expressed on myeloid cells (monocytes, macrophages, granulocytes, and dendritic cells) and neurons. The ligand for rat SIRP is CD47, which is similar to the interaction of the human homolog SIRPα1 (CD172α) and human CD47. The SIRP/CD47 interaction is thought to be important in maintaining cellular adhesion and possibly promote T-cell activation.
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).
