| | Progesterone Receptor Fluorescence Polarization Assay |
| Description: | Compounds are added to the 384 well black low-volume plates to a final volume of 0.1 μL. DTT and DMSO are added to the chilled assay buffer just before beginning assay. Sufficient Fluormone PL Red and PR-LBD are defrosted on ice and added to the chilled buffer in a glass tube to give a final concentration of 2 nM and 8 nM, respectively. A volume of 10 μL of the assay mix is added to compound plates with a multidrop. The assay is allowed to incubate at 20-22° C. (room temp) for 2-3 hours. The plates are counted in a Discovery Analyst with suitable 535 nM excitation and 590 nM emission interference filters (Dichroic 561 nM). Compounds that interact with the PR result in a lower fluorescence polarization reading. Test compounds are dissolved and diluted in DMSO. |
