GreenGlo \u2122, 20,000X in Water, is a non-carcinogenic and non-toxic alternative to Ethidium bromide used for the detection of nucleic acids in agarose gels. It is as sensitive as Ethidium bromide. There is no toxic DMSO as GreenGlo \u2122 is supplied in water. \n \nGreenGlo \u2122 has fluorescence excitation maxima at 295 nm and 490 nm. The fluorescence emission maxima is similar to EtBr when bound to DNA \u2013 at 530 nm.
