Hoechst 33342, CAS 23491-52-3

Description: Hoechst dyes are cell membrane-permeant, minor groove-binding blue fluorescent DNA stains. Hoechst dyes are widely used in cell cycle and apoptosis studies and also as nuclear counterstains. Hoechst 33342 is reported to be slightly more membrane-permeable than Hoechst 33258. Either dye can be used to stain live or fixed cells in buffer or medium at 1 ug/mL with no wash step. Biotium also offers Hoechst 33342, 10 mg/mL in H2O.
