Application

N-[4-(5,6-Dimethoxy-N-phthalimidinyl)phenyl]maleimide (DPM) is used to fluorescence label proteins via their sulfhydryl groups. Nonfluorescent N-substituted maleimides react selectively with thiol compounds to form fluorescent derivatives. Fluorescent intensity of the dimethoxyphthalimidyl group is higher than that of the non substituted phthalimidyl group.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
