Cluster of Differentiation 34 (CD34), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in performing cell based assays. It can also be used as a protein standard, or in other research applications.

  • Activity: Measured by the ability of the immobilized protein to support the adhesion of the HUVEC human umbilical vein endothelial cell line; when 4 x 104 cells/well are added to human CD34 coated plates (100μL/well of a 0.8μg/mL solution), >40 % will adhere after one hour at 37°C
  • Formulation: Lyophilized in 140mM NaCl, 2.7mM KCl, 10mM Na2HPO4, 1.8mM KH2PO4, pH 7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween 80
  • Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 0.2mg/mL or lower; aliquot and use as soon as possible
