Hoechst 33342 Solution (20 mm), High-Quality Hoechst Dye Solution For Fluorescent Staining Of Dna And Nuclei In Fixed- Or Live-Cell Imaging Techniques, Each

Details:

Thermo scientific™ pierce 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.Hoechst 33342 (2'-[4-ethoxyphenyl]-5-[4-methyl-1-piperazinyl]-2,5'-bi-1h-benzimidazole trihydrochloride trihydrate) is a cell-permeable dna stain that is excited by ultraviolet light and emits blue fluorescence at 460 to 490nm. Hoechst 33342 binds preferentially to adenine-thymine (a-t) regions of dna. This stain binds into the minor groove of dna and exhibits distinct fluorescence emission spectra that are dependent on dye:base pair ratios.
