| 描述 | Hoechst 33258 analog 5 is a nuclear marker dye in Hoechst series, primarily binding to the A/T-rich regions of DNA strands. Its binding affinity is not restricted to DNA, but the fluorescence intensity is significantly enhanced when bound to A/T-rich double-stranded DNA, making it a valuable tool for live cell labeling. The fluorescence intensity of Hoechst dye increases with the solution's pH, enabling its application across a range of biological research fields[1]. |
