DNA Stain

DNA stains are fluorescent dyes that bind double-stranded DNA to label cell nuclei and chromatin. The listed products are mainly bisbenzimide dyes of the Hoechst family, which bind the minor groove of DNA at adenine-thymine (A-T) rich sequences. Bound dye fluoresces blue under ultraviolet excitation, so nuclei stand out clearly against the surrounding cytoplasm. Hoechst dyes stain both fixed and living cells without permeabilization. They serve as nuclear counterstains in fluorescence microscopy and as DNA content probes in cell cycle analysis. Condensed, brightly stained chromatin also helps to identify apoptotic nuclei. Hoechst 33258 trihydrochloride is the parent dye, listed with the related bisbenzimide HOE 33187 and related compounds such as Hoechst 33258 analog.

  • Ethidium bromide
    Cat. No.
    A17287

    Ethidium bromide

    Synonyms: EtBr; Homidium bromide

    Ethidium bromide is a fluorescent intercalating agent widely used in molecular biology as a nucleic acid stain. It inserts between DNA base pairs, allowing visualization of DNA and RNA under ultraviolet (UV) light during techniques such as agarose gel electrophoresis. Due to its high sensitivity and strong fluorescence, Ethidium bromide is a standard tool for nucleic acid detection, though it is handled with caution because of its mutagenic properties.
