Zastosowanie

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

Działania biochem./fizjol.

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

Cell Cycle Analysis Using a Nucleoside Triphosphate (NTP) Transporter Molecule for Rapid DNA Labeling in Living Cells

Regulation of the cell cycle involves processes crucial to the survival of a cell, including the detection and repair of genetic damage as well as the prevention of uncontrolled cell division associated with cancer. The cell cycle is a four-stage process in which the cell 1) increases in size (G1-stage), 2) copies its DNA (synthesis, S-stage), 3) prepares to divide (G2-stage), and 4) divides (mitosis, M-stage). Due to their anionic nature, nucleoside triphosphates (NTPs), the building blocks of both RNA and DNA, do not permeate cell membranes.
