bisbenzimide H-33342 trihydrochloride (Hoechst 33342) 10 mg/mL in water

bisbenzimide H-33342 trihydrochloride (Hoechst 33342)

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.

For ease of use and safer handling
λEx/λEm (with DNA) = 350/461 nm
Light yellow solution
Store at 4°C and protect from light

Hoechst can be used to stain live bacteria (gram-positive and gram-negative) but in live yeast the staining is weak and not nuclear.
