METHOD OF IDENTIFYING LIGANDS FOR NUCLEAR RECEPTORS

摘要

The present invention provides a method of identifying a ligand to a nuclear receptor protein comprising wherein said nuclear receptor protein is first expressed in an eukaryotic expression system in the presence of at least one candidate ligand. The nuclear receptor protein is then purified, isolated and mass spectrometry is used to determine the presence of a bound ligand. The ligand is finally isolated and the measured spectra is compared with the spectra of known ligands in compound libraries to identify the ligand.
