Hoechst 33258 is a Hoechst stain used to stain DNA. It is part of a family of fluorescent dyes. Dyes and metabolites.

Hoechst 33258 is useful for staining DNA, chromosomes and nuclei. The nucleic acid binds to the minor groove of DNA at AT-rich sequences. This dye is commonly used for determining the DNA content of viable cells without detergent treatment or fixation and for fluorescence

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 (Cat. No. 382065) have been used in conjunction with RNA aptamers in the 5′ untranslated region (UTR) to control expression of transfected gene constructs.

bisBenzimide H 33258 is a potent and selective Bcl-XL inhibitor. bisBenzimide H 33258 is a membrane-permeable, fluorescent DNA stain with low cytotoxicity that intercalate in A-T regions of DNA.
