Abstract
The invention concerns scintillation proximity assays performed in multiwell plates where a charge coupled device is used to image the wells. Conventional phosphors emit blue light (350-450 nm) which is absorbed by yellow or brown assay components. This problem is addressed by the use of phosphors that emit radiation of longer wavelength (480-900 nm).
