GelGreen

GelGreen is an intercalating nucleic acid stain used in molecular genetics for agarose gel DNA electrophoresis. GelGreen consists of two acridine orange subunits that are bridged by a linear oxygenated spacer.[1][2]

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Its fluorophore, and therefore its optical properties, are essentially identical to those of other N-alkylacridinium orange dyes. When exposed to ultraviolet light, it will fluoresce with a greenish 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] GelGreen is sold as a solution in either DMSO or water.[3]
