Cluster of Differentiation 55 (CD55), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in analysis of protein structure, studying protein-protein interactions, and cell biology research applications. It can also be used as an immunogen, or as a protein standard.

  • Activity: Measured by its binding ability in a functional ELISA; immobilized human CD55 at 2μg/mL (100μL/well) can bind human CD97 with a linear range of 1.28-32ng/mL
  • Formulation: Lyophilized in PBS, pH 7.4, 5% Mannitol, 5% Trehalose, and 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

Shipping Condition: Room Temperature. This protein is manufactured by Sino Biological Inc.
