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. 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.
  2. Researchers should determine the optimal concentration of this reagent for their individual applications.
  3. 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.
  4. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  5. 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.
  6. An isotype control should be used at the same concentration as the antibody of interest.
  7. 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.
  8. Please refer to http://regdocs.bd.com to access safety data sheets (SDS).
  9. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  10. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  11. Cy is a trademark of Global Life Sciences Solutions Germany GmbH or an affiliate doing business as Cytiva.
  12. 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.

16A1

The 16A1 monoclonal antibody specifically recognizes human CD140a which is also known as human platelet derived growth factor receptor α (PDGFRα). CD140a (PDGFRα) is an ~170 kDa single pass type I transmembrane glycoprotein that is encoded by PDGFRA (platelet derived growth factor receptor alpha) which belongs to the receptor tyrosine kinase (RTK) class III family. This receptor is comprised of an N-terminal extracellular domain with five IgC2-like domains, and a transmembrane sequence followed by a cytoplasmic region with a split tyrosine kinase domain. CD140a (PDGFRα) is expressed on a variety of cell types including platelets, monocytes, fibroblasts, endothelial cells, smooth muscle cells, glial cells, chondrocytes as well as numerous tumor cell types. PDGFRα dimerizes and autophosphorylates when binding to homodimeric or heterodimeric platelet-derived growth factors (PDGF) comprised of disulfide-bonded A, B, or C (but not D) isoforms, ie, PDGF-AA, PDGF-AB, PDGF-BB, and PDGF-CC. PDGFRα can also heterodimerize with platelet derived growth factor receptor β (PDGFRβ, also known as CD140b) and autophosphorylate upon binding to PDGF-AB, PDGF-BB, and possibly PDGF-CC and PDGF-DD. Homodimerized CD140b (PDGFRβ) is activated by PDGF-BB and PDGF-DD. PDGF ligands stimulate the growth, proliferation, migration, and survival of PDGF Receptor-positive normal cells as well as tumor cells. CD140a (PDGFRα) plays key roles in multiple processes including embryonic development, wound healing, and the regulation of platelet activation.

RB780
The BD Horizon RealBlue™ 780 (RB780) 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 781-nm. Driven by BD innovation, RB780 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), RB780 can be used as an alternative to PE-Cy7 and we recommend using an optical filter centered near 780-nm (eg, a 780/60-nm bandpass filter). For spectral instruments equipped with a Blue laser (488-nm), it can be used in conjunction with PE-Cy7. RB780 is on average brighter than PE-Cy7 and has minimal spillover into Yellow-Green detectors.
