Phosphate buffered saline with gelatin and 0.1% sodium azide.


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 APC under optimum conditions, and unconjugated antibody and free APC were removed. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.

Clone My10: The monoclonal antibody is supplied as 100 µg purified immunoglobulin in 2.0 mL (50 µg/mL) of phosphate-buffered saline (PBS).

Clone 8G12: The monoclonal antibody is supplied as 50 µg purified immunoglobulin in 2.0 mL (25 µg/mL) of PBS. The FITC and PE conjugates are each supplied as 50 µg in 2.0 mL (25 µg/mL) of PBS. The PerCP conjugate is supplied as 50 µg in 1.0 mL (50 µg/mL) of PBS. The PerCP-Cy5.5 conjugate is supplied as 12.5 µg in 1.0 mL (12.5 µg/mL) of PBS. The PE-Cy7 conjugate is supplied as 25 µg in 0.5 mL (50 µg/mL) of PBS. The APC conjugate is supplied as 50 µg in 0.5 mL (100 µg/mL) of PBS. PBS contains gelatin and 0.1% sodium azide. Store vials at 2° to 8°C. Conjugated forms should not be frozen and should be protected from prolonged exposure to light. Each reagent is stable for the period shown on the bottle label when stored as directed.


  1. Please refer to for technical protocols.
  2. 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.
  3. This APC-conjugated reagent can be used in any flow cytometer equipped with a dye, HeNe, or red diode laser.

Down Arrow Up Arrow

The CD34 antibody, clone 8G12 (Anti–HPCA-2), is derived from the hybridization of Sp2/0-Ag14 mouse myeloma cells with spleen cells of BALB/c mice immunized with the human cell line KG-1a.

The CD34 antibody recognizes a 105–120-kilodalton (kDa) single-chain transmembrane glycoprotein. Clone 8G12 recognizes an epitope on CD34 distinct from the one recognized by clone My10; at least three epitopes have been identified.

R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE is designed to be excited by the Blue (488 nm), Green (532 nm) and Yellow-Green (561 nm) lasers and detected using an optical filter centered near 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
