Hoechst 33342 analog

Uses

Hoechst 33342 analog is a marker dye in Hoechst series. Hoechst is A live nuclear marker dye. Hoechst binds to the grooves in the DNA double strand, which tends to be A/ T-rich DNA strand. Although it binds to all nucleic acids, the A/ T-rich double strand DNA significantly enhances fluorescence intensity Therefore,Hoechst dye can be used for living cell labeling. The fluorescence intensity of Hoechst dye increases with the increase of pH of solution[1].

Safety Profile

Mutation data reported. Whenheated to decomposition it emits toxic vapors of NOx andCl-.
