ApplicationA bibenzimidazole dye that has been utilized as a fluorescent stain. It is membrane-permeable and selectively binds to adenine-thymine regions in the minor groove of B-form DNA 1,2 with a high binding constant, making it a useful stain for DNA, chromosomes, and nuclei 3,4. It has been shown that the fluorescence is relatively insensitive to the presence of various solution reagents (i.e., BSA, RNA, Tris, sucrose, TEA/EDTA, Triton X-100, and SDS)5. Furthermore, the solution ionic strength and pH has been shown to be independent of the Stokes’ shift of bisBenzimide H 33258 3. The properties of this dye make it useful in several applications such as detecting mycoplasma contamination in tissue culture 6,7, indicating early onset of apoptosis8,9, sorting living cells based on DNA content, and acting as a probe for DNA-Drug interactions3.
