    摘要: An in vitro assay method permits the identification of a test substance which inhibits the mutual association of a pair of proteins. The method includes the steps of providing a pair of proteins capable of mutual association, one of said proteins bearing a covalently linked fluorophore; preparing a mixture containing the two proteins and at least one test substance; irradiating the mixture with polarized light of a suitable wavelength permitting excitation of the fluorophore as indicated by emission of polarized light; measuring the degree of polarization of the emission, and determining the effect of the presence or concentration of the test substance in decreasing the observed emission polarization of a mixture of the two proteins alone. Inhibitory activity of in the test substance correlates with decreased depolarization values.
