Hoechst 33258 trihydrochloride (Synonyms: bisBenzimide H 33258 trihydrochloride; H 33258 trihydrochloride)
- 目录号: TD-15558A 纯度: 98.87%
生物活性 | Hoechst 33258 trihydrochloride 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]. | ||||||||||||||||
