GelRed is an intercalating nucleic acid stain used in molecular genetics for agarose gel DNA electrophoresis. GelRed structurally consists of two ethidium subunits that are bridged by a linear oxygenated spacer. [1] [2]
GelRed is a fluorophore, and its optical properties are essentially identical to those of ethidium bromide. When exposed to ultraviolet light, it fluoresces with an orange color that strongly intensifies after binding to DNA. [3] The substance is marketed as a less toxic and more sensitive alternative to ethidium bromide. [3] GelRed is sold as a solution in anhydrous DMSO or ultrapurified water. [3] GelRed is unable to cross cell membranes. [4]
