Supplier: MP Biomedicals

A membrane permeable, low cytotoxic fluorescent supravitol dye, reversibly binding to DNA, staining the AT-rich regions of the double stranded DNA. It has been shown to displace several known DNA intercalators. Adriamycin interferes with dye uptake.

bisbenzimide H-33342 trihydrochloride (Hoechst 33342) ≥98%

Supplier: Biotium

Hoechst dyes are cell membrane-permeant, minor groove-binding blue fluorescent DNA stains. Hoechst dyes are widely used in cell cycle and apoptosis studies and also as nuclear counterstains. Hoechst 33342 is reported to be slightly more membrane-permeable than Hoechst 33258, but either dye can be used to stain live or fixed cell in buffer or medium at 1 ug/mL, with no wash step required.

Supplier: Invitrogen

Hoechst 33342 fluorescent stain is a high-quality solution of Hoechst dye for fixed- and live-cell fluorescent staining of DNA and nuclei in cellular imaging techniques.

Supplier: Adipogen

Useful for staining DNA, chromosomes and nuclei. May be used for fluorescence microscopy or flow cytometry. Suitable for vital DNA staining of a variety of cell types and as a probe of membrane permeability in mammalian cells.
