Description
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.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.
1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
2. Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
3. 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.
4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
5. An isotype control should be used at the same concentration as the antibody of interest.
6. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
7. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
8. Human donor specific background has been observed in relation to the presence of anti-polyethylene glycol (PEG) antibodies, developed as a result of certain vaccines containing PEG, including some COVID-19 vaccines. We recommend use of BD Horizon Brilliant™ Stain Buffer in your experiments to help mitigate potential background.

9. Researchers should determine the optimal concentration of this reagent for their individual applications.
10. 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.
