| Description: | Determination of In Vitro Pharmacological Activity. The human androgen receptor (AR) assay was run using Product #IB03001 from Indigo Biosciences. The cell line provided in this kit carries a reporter gene, induced upon AR stimulation. This reporter gene is cDNA encoding for beetle luciferase, a 62 kD protein originating from the North American firefly (Photinus pyralis). This luciferase catalyzes the mono-oxidation of D-luciferin yielding oxyluciferin, adenosine monophosphate, pyrophosphate, CO2, and photon emission. The luminescence intensity of the reaction is quantified using a luminometer. To run the assay, the cells are thawed by adding pre-warmed cell recovery medium to each tube, then placed in a 37° C. water bath. 30000 viable cells in 200 μl are plated (collagen coated plates) and incubated at 37° C., ≥85% humidity, 5% CO2 for 24 hours. Media is replaced with compound screening medium. Cells are then challenged with 125 pM (EC80) 6a-Fl Testosterone and compounds are applied in half logarithmic dilutions from 10 μM to 10 nM. Assay plates are then incubated at 37° C., ≥85% humidity, 5% CO2 for 22-24 hours. Media is replaced with luciferase detection reagent and allowed 5 minutes to equilibrate prior to luminescence quantification. Data Analysis consisted of calculating percentage of control between 100% (Negative control:6a-Fl Testosterone) and 0 (positive control: no 6a-FL Testosterone). Fitting of normalized values was made 4-Parameter sigmoidal binding curve (Log[conc]) vs. signal. |
