Ciliary Neurotrophic Factor (CNTF), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as protein structure analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

  • Activity: Measured by its binding ability in a functional ELISA: 1. Immobilized human CTNFR at 10μg/mL (100μL/well) can bind human CNTF with a linear ranger of 1.28-160ng/mL; 2. Immobilized Rat CTNFR at 10μg/mL (100μL/well) can bind human CNTF with a linear range of 1.28-160ng/mL
  • 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
