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 with BD Horizon BV650 under optimal conditions that minimize unconjugated dye and antibody.

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

  1. This antibody was developed for use in flow cytometry.
  2. 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.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  7. Please refer to for technical protocols.

The MD22 monoclonal antibody specifically recognizes CD64 which is also known as Fc-gamma receptor I (FcgR1) or FcγRI. CD64 is a ~72 kDa type I transmembrane glycoprotein that is encoded by FCGR1A (Fc fragment of IgG receptor Ia). CD64 functions as a high affinity receptor for human IgG. The CD64 antigen is expressed on monocytes, macrophages, at low levels on polymorphonuclear neutrophils (PMNs), and on a subpopulation of circulating dendritic cells. The CD64 antigen is an early granulomonocytic lineage marker on CD34+ hematopoietic progenitors. Expression of the CD64 antigen increases transiently in cases of sepsis. The CD64 antigen functions in both innate and adaptive immune responses, and mediates endocytosis, phagocytosis, antigen presentation, antibody-dependent cellular cytotoxicity, cytokine release, and superoxide generation. The CD64 antigen associates with the signal-transducing γ-chain homodimer of Fc receptors to form the functional high affinity FcγRI complex. Ligation of the CD64 antigen leads to the activation of the protein tyrosine kinases, hck and lyn.

The antibody was conjugated to BD Horizon™ BV650 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 650-nm.  BD Horizon BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter).  Due to the excitation and emission characteristics of the acceptor dye, there will be  spillover into the APC and Alexa Fluor® 700 detectors.  However, the spillover can be corrected through compensation as with any other dye combination.

The BD Horizon Brilliant Violet™ 650 (BV650) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This tandem fluorochrome is comprised of a BV421 donor with an excitation maximum (Ex Max) of 406-nm and an acceptor dye with an emission maximum (Em Max) at 649-nm. BV650, driven by BD innovation, is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 650-nm (e.g., a 660/20-nm bandpass filter). The acceptor dye can be excited by the Red (628–640-nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
