Article: New zoology study findings have been reported from Hirosaki University.(Report)

According to recent research from Aomori, Japan, "Chromosomes stained with fluorochromes, including quinacrine mustard (QM), emit the brightest fluorescence immediately after exposure to excitation light, and the fluorescence gradually fades with an increase in exposure time. However, in the QM-stained chromosomes of the small Japanese field mouse Apodemus argenteus, most C-heterochromatic regions emit weak fluorescence immediately after exposure to blue light, and they become brightly fluorescent by prolonged exposure (delayed QM fluorescence)."

"We proposed recently that the delayed QM fluorescence is somehow related to nicks produced in C-heterochromatic DNA ...
