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).
