General description

Quinacrine mustard dihydrochloride is a fluorescent acridine dye, also abbreviated as QM. In an aqueous solution, the chloroethyl groups rapidly lose chloride ions yielding aziridinium cations. These readily react with the carboxyl, thiol, and heterocyclic ring nitrogen groups of proteins and nucleic acids, or with other nucleophiles.

Application

Quinacrine mustard dihydrochloride is used to stain metaphase chromosomes. Recent applications include the Q-banding of maize and karyotyping of fish. The dye is also used as a vital stain for trypanosomes.

"Delayed QM-fluorescence" refers to the unusual kinetics of fluorescence from most of the C-heterochromatic regions of the chromosomes of the small Japanese field mouse Apodemus argenteus. When stained with quinacrine mustard (QM-stained), these C-heterochromatic regions emit weak fluorescence immediately after
