설명

애플리케이션

Bisbenzimide Hoechst 33342 is a specific stain for AT-rich regions of double-stranded DNA and has been shown to displace several known DNA intercalators. This fluorescent dye has been used in sorting living cells based on DNA content, used in flow cytometry for the determination of DNA content, and for the visualization of chromatin distribution in living cells. It has been used to detect BrdU incorporation into cells and in studying the initial stages apoptosis and cellcycle distribution.^, Chromosomes that are dividing or replicating will not stain with this dye.

Useful for staining DNA, chromosomes and nuclei. May be used for fluorescence microscopy or flow cytometry.
Excitation max. = 346 nm
Emission max. = 460 nm

생화학적/생리학적 작용

Membrane-permeable, fluorescent DNA stains with low cytotoxicity that intercalate in A-T regions of DNA.
