| Description: | 50 mM HEPES buffer (pH 7.4); 150 mM NaCl; 1 mM DTT; 5 mM MgCl2; 0.01% BSA; 5% DMSO; 0.6 ug/mL RORc receptor; 6 nM 25-[3H]hydroxycholesterol. For NSB wells, 1 uM 25-hydroxycholesterol was also present. Assay plates were 96-well polypropylene V-bottom plates. 10 uL of 5× compound in 25% DMSO/75% Assay Buffer was added to Test wells. 10 uL of 25% DMSO/75% Assay Buffer was added to Total Binding or No Receptor wells. 10 uL of 5 uM 25-hydroxycholesterol in 25% DMSO/75% Assay Buffer was added to NSB wells. 20 uL of 15 nM 25-[3H]hydroxycholesterol prepared in Assay Buffer was added to all wells. 20 uL of 1.5 ug/mL RORc receptor was added to wells (or 40 uL Assay Buffer to No R wells). Following addition to the wells, the plates were incubated 3 h at 25° C. Filtration |
