td style=margin: 0px; padding: 5px 15px; text-align: justify; border-style: solid; border-color: rgb(229, 229, 229);The assay is performed in a total volume of 1 mL at 37 ℃. Unless otherwise noted, the incubation mixture contains 11 nM [4-nbsp;span style=margin: 0px; padding: 0px; position: relative; vertical-align: baseline; top: -0.5em;14/spanC] androstene-3, 17-dione ([4-nbsp;span style=margin: 0px; padding: 0px; position: relative; vertical-align: baseline; top: -0.5em;14/spanC]A), 24 mM NADPH (tetrasodium salt Type III), the appropriate concentrations of the desired inhibitor, and 120 mu;g of microsomal protein. The (4-nbsp;span style=margin: 0px; padding: 0px; position: relative; vertical-align: baseline; top: -0.5em;14/spanC)A is added as a solution in 1.7% ethanol in 0.05 M potassium phosphate buffer (pH 7.4), so that the final concentration of ethanol does not exceed 0.02% (v/v). The reaction is started by the addition of enzyme and stopped after 20 min by the addition of 7 vol of ethyl acetate. The mixture is agitated on a vortex mixer and centrifuged at 600 g for 5 min. The aqueous phase is re-extracted with 7 vol of ethyl acetate, and the combined extracts are evaporated to dryness using an Evapo-Mix. Over 99% of the radio- active of [4-nbsp;span style=margin: 0px; padding: 0px; position: relative; vertical-align: baseline; top: -0.5em;14/spanC] added is recovered using this extraction system. The residue obtained is dissolved in 150 mu;L acetone, and 100 mu;L aliquots are chromatographed for 65 min on thin-layer plates precoated with silica gel 60 using ethyl: acetate: isooctane (140:60, v/v; system A) or toluene: chloroform: methanol (70:140:20; system B). The radioactive zones of the plate are located with a Berthold LB 2760 thin-layer scanner. The radioactive estradiol (E2) and estrone (E1) neaks are identified by comparison with authentic standards. The corresponding bonding band of silica gel is transferred to vials containing 10 mL of scintillation fluid, and counted with a 6880 Liquid Scintillation system./td
