Overview

Membrane-permeable, adenine-thymine-specific fluorescent stain. Useful for staining DNA, chromosomes, and nuclei. Increases the rate of channel-mediated Ca2+ efflux from junctional cytoplasmic reticulum vesicles. Can also be used to detect mycoplasma contamination in tissue culture. H 33258 and the related compound H 33342  have been used in conjunction with RNA aptamers in the 5′ untranslated region (UTR) to control expression of transfected gene constructs.
