Hoechst 33342, 10mg/mL in H2O

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. </p> <ul> </p> <li> lamba;_Ex/ lamba;_Em(with DNA) = 350/461 nm</li> </p> <li>Light yellow solution</li> </p> <li>Store at 4°C and protect from light</li> </p> <li>C₂₇H₃₁Cl₃N₆O</li> </p> <li>MW: 561.93</li> </p> <li>[23491-52-3]</li> </p> </ul>
