Preparation And Storage

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.

Recommended Assay Procedures

BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
  3. For U.S. patents that may apply, see bd.com/patents.
  4. 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.
  5. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  6. 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.
  7. 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. For more information visit https://www.bdbiosciences.com/en-us/support/product-notices.
  8. When using high concentrations of antibody, background binding of this dye to erythroid fragments produced by ammonium chloride-based lysis, such as with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899), has been observed when the antibody conjugate was present during the lysis procedure. This may cause nonspecific staining of target cells, such as leukocytes, which have bound the resulting erythroid fragments. This background can be mitigated by any of the following: titrating the antibody conjugate to a lower concentration, fixing samples with formaldehyde, or removing erythrocytes before staining (eg, gradient centrifugation or pre-lysis with wash). This background has not been observed when cells were lysed with BD FACS™ Lysing Solution (Cat. No. 349202) after staining.
  9. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  10. An isotype control should be used at the same concentration as the antibody of interest.
  11. Cy is a trademark of Global Life Sciences Solutions Germany GmbH or an affiliate doing business as Cytiva.
  12. Please observe the following precautions: We recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to protect exposure of conjugated reagents, including cells stained with those reagents, to any room illumination. Absorption of visible light can significantly affect the emission spectra and quantum yield of tandem fluorochrome conjugates.

U23-56

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.

RB705
The BD Horizon RealBlue™ 705 (RB705) Dye is part of the BD® family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 498-nm and an emission maximum (Em Max) at 707-nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RB705 can be used on both spectral and conventional cytometers and is designed to be excited by the Blue laser (488-nm) with minimal excitation by the 561-nm Yellow-Green laser. For conventional instruments equipped with a Blue laser (488-nm), RB705 can be used as an alternative to PerCP-Cy5.5 or BB700 and we recommend using an optical filter centered near 710-nm (e.g., a 695/40 or 710/50-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PerCP-Cy5.5. RB705 is on average brighter than PerCP-Cy5.5 and BB700, and has minimal spillover into Yellow-Green detectors.
