| Description: | Using cytosol from progesterone receptor-expressing insect cells (Hi5), competitive binding to the progesterone receptor was determined from the ability to displace 3H-progesterone as reference substance from the receptor. If a compound has an affinity corresponding to progesterone, this corresponds to a competition factor (CF) of 1. CF values greater than 1 are characterized by a lower affinity for the progesterone receptor, and CF values of less than 1 are characterized by higher affinity. |
