What is a good nuclear stain for live imaging?

Nettet6. mai 2024 · Answer Yes, Hoechst can stain live cells. Hoechst 33528 and Hoechst 33342 are both cell membrane permeant, which makes both suitable for staining live cells. Both dyes are also less toxic than most other dyes, which ensures a higher viability of stained live cells.
