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. 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.
  8. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  9. An isotype control should be used at the same concentration as the antibody of interest.
  10. 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.
  11. Tandem fluorochromes contain both an energy donor and an energy acceptor. Although every effort is made to minimize the lot-to-lot variation in the efficiency of the fluorochrome energy transfer, differences in the residual emission from the donor may be observed. Additionally, multi-laser cytometers may directly excite both the donor and acceptor fluorochromes. Therefore, we recommend for every tandem conjugate, a matched individual single-stain control be acquired for generating a compensation or spectral unmixing matrix.

512

The 512 monoclonal antibody specifically recognizes a 65-kDa and 55-kDa molecules of the erythrocyte membrane, which are the rat counterpart of mouse Crry/p65, a membrane inhibitor of complement component C3 convertase. Crry/p65 is widely distributed, predominantly expressed on endothelial cells and all circulating cells. This molecule was also detected on immature hepatocytes, systemic endothelial cells, skin fibroblasts, bronchial epithelial cells, bile canaliculi, the Schwann sheath of peripheral nerve fibers, and ependymal cells. Mouse Crry/p65 uses the same mechanisms as human Decay-Accelerating Factor (DAF) and human Membrane Cofactor Protein (MCP) in inhibiting C3 and C5 convertases, but it is not homologous to either DAF or MCP. It has been proposed that Crry/p65 is the mouse genetic homologue of human CR1 (CD35).

RB670
The BD Horizon RealBlue™ 670 (RB670) Dye is part of the BD® family of blue dyes. It is a tandem fluorochrome with an excitation maximum (Ex Max) at 492 nm and an emission maximum (Em Max) at 670 nm as measured using an antibody-dye conjugate. Driven by BD® innovation, RB670 can be used on both spectral and conventional cytometers and is designed to be primarily excited by the Blue laser (488-nm). For conventional instruments equipped with only a Blue laser (488-nm), RB670 can be used as an alternative to PE-Cy5 and we recommend using an optical filter centered near 670-nm (eg, a 670/30-nm bandpass filter). For conventional and spectral instruments equipped with both a Blue (488-nm) and Yellow-Green (561-nm) laser and appropriate detectors, it can be used in conjunction with PE-Cy5.
