Abstract

Long wavelength, narrow emission bandwidth fluorecein dyes are provided for detecting specially overlapping target substances. The dyes comprise 4,7-dichlorofluoresceins, and particularly 2′,4′,5′,7′-tetrachloro-4,7-dichloro-5-(and 6-) carboxyfluoresceins. Methods and kits for using the dyes in DNA analysis are provided.
