Hoechst 33342 (hydrochloride) (solution)

Hoechst 33342 is a fluorescent DNA probe. It forms a fluorescent complex by binding to the minor groove of adenine and thymine-rich sequences. Hoechst 33342 displays an emission maximum of 465 when bound to dsDNA upon excitation at 350 nm. It has been used as a marker of nuclei in cell cycle studies and to distinguish nuclear morphology in apoptotic cells.Formal Name: 2'-(4-ethoxyphenyl)-5-(4-methyl-1-piperazinyl)-2,5'-bi-1H-benzimidazole, trihydrochloride.
