Abstract

Long wavelength, narrow emission bandwidth fluorecein dyes are provided for detecting spacially overlapping target substances. The dyes comprise 4,7-dichlorofluoresceins, and particularly 1',2',7',8'-dibenzo-4,7-dichlorofluoresceins. Methods of using the dyes in automated DNA sequencing are described.
