Assay Method Information

Assay Name:  Erythropoietin (EPO) Biological Assay
Description:  The activities of compounds of the invention in inducing erythropoietin (EPO) production were assessed by using human live cancer cell strain Hep3B (ATCC: American type culture collection, Manassas, Va.). Hep3B cells seeded in a 96-well plate with a density of 2.5104 cells/well were cultivated overnight in DMEM culture medium (Dulbecco's Modified Eagle's Medium) at 37 C. in the presence of 10% fetal bovine serum (FBS). The next day, the supernatant liquid of culture medium was abandoned by suction, and to the residue was added fresh DMEM (containing 0.5% DMSO, 0.5% FBS) containing compound of the invention with a series of concentrations (0.31160.00 μM) or containing solvent used for comparison. The cells were cultivated at 37 C. for 24 h. The supernatant liquid was collected and the EPO concentration of the supernatant was quantified by using human EPO ELISA kit (Abcam). The activity of each compound in inducing erythropoietin (EPO) production was represented by half maximal effective concentration (EC50).
