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 U23-56 monoclonal antibody specifically binds to Macrophage scavenger receptor 1 (MSR1) which is also known as CD204, Scavenger receptor A (SRA), Scavenger receptor class A member 1 (SCARA1), or Macrophage acetylated LDL receptor I and II. MSR1 is a trimeric type II transmembrane glycoprotein that belongs to the type 1 class A scavenger receptor family. MSR1 functions as a scavenger receptor that enables mononuclear phagocytes to take up and respond to a variety of negatively charged macromolecules including oxidized and acetylated low density lipoproteins. MSR1 also functions in innate immunity as a pattern recognition receptor. MSR1 allows macrophages to recognize and respond to microbial products, such as lipopolysaccharide and polyribonucleic acids, by the production of cytokines and inflammatory mediators. MSR1 also reportedly serves as a coreceptor that regulates the signaling of some Toll-like receptors including TLR-3, TLR-4, and TLR-9. MSR1 has been associated with several diseases including atherosclerosis, Alzheimer's disease, ischemic injury, and sepsis. The U23-56 antibody was tested by flow cytometric and Western blot analyses of MSR1-transfected and untransfected cells to verify its specificity.
The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.
