| For ease of use and safer handling, we offer both Hoechst 33258 and Hoechst 33342 dissolved in H2O at 10 mg/mL. 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, but either dye can be used to stain live or fixed cell in buffer or medium at 1 ug/mL, with no wash step required. &lamba,Ex/&lamba,Em (with DNA) = 350/461 nm Light yellow solution Store at 4C and protect from light C27H31Cl3N6O MW: 561.93 [23491-52-3] |
