Descripción general

Hoechst 33258, also known as bisbenzimide, is a fluorescent blue dye. It is categorized as a chromosomal stain that binds to the minor groove of the DNA double helix recognizing a run of four A-T base pairs.

Aplicación

Hoechst 33258 is used to estimate DNA concentration in samples by fluorometry which is better than spectrophotometry, allowing the determination of nanogram quantities of DNA. Also, Hoechst 33258 is suitable to detect mycoplasma contamination in cell cultures due to its high fluorescence ability.
