A bromoaryltetrazole-modified uridine was synthesized as a new RNA building block for bioorthogonal, light-activated and postsynthetic modification with commercially available fluorescent dyes. It allows “photoclick”-type modifications by irradiation with light (300 nm LED) at internal and terminal positions of presynthesized RNA with maleimide-conjugated fluorophores in good yields. The reaction was evidenced for three different dyes. During irradiation, the emission increases due to the formation of an intrinsically fluorescent pyrazoline moiety as photoclick product. The fluorogenecity of the photoclick reaction was significantly enhanced by energy transfer between the pyrazoline as the reaction product (poor emitter) and the photoclicked dye as the strong emitter. The RNA-dye conjugates show remarkable fluorescent properties, in particular an up to 9.4 fold increase of fluorescence, which are important for chemical biology and fluorescent imaging of RNA in cells.

Requirements for flow cytometry of metaphase chromosomes stained with three deoxyribonucleic acid (DNA)-specific fluorescent dyes--Hoechst 33258, Chromomycin A3, and ethidium bromide--are reviewed. Fluorescence properties of these three stains when bound to mitotic cells or to chromosomes in suspension are measured and compared with fluorescence properties when bound to DNA in solution. Conditions are given for high resolution flow cytometry of Chinese hamster chromosomes stained with each of the fluorophors, and histograms are presented that exhibit differences in relative peak position and area. Energy transfer fluorescence between two DNA stains is presented as a potentially useful new parameter for flow cytometry of chromosomes and is illustrated by fluorescence energy transfer from Chromomycin A3 to ethidium bromide when simultaneously bound to hamster mitotic cells.
