Assay Method Information

Assay Name:  Competitive Ligand Binding Assay, GR-Mediated Agonist Activity Assay, and IL-6 Repression Assay
Description:  Competitive Ligand Binding Assay- The Ki values were determined by the application of the Cheng-Prusoff equation: Ki=IC50/(1+[L]/Kd) where [L] is the concentration of labeled ligand and Kd is the dissociation constant of the labeled ligand determined in the saturation analysis. GR-Mediated Agonist Activity Assay- GR-mediated activation by compounds is measured against maximal activation of dexamethasone in the same experiment and reported as % relative efficacy. Potencies of compounds are reported as the concentration at which they reach half their agonist (EC50). IL-6 Repression Assay- The GR-mediated repression of IL-6 production in a human fibroblast (NHDFneo) cell line is measured with a modified ELISA assay.
