Description

General description

Orange G is an azo dye[1] that is acidic in nature.[2] It is widely used as a tracking dye for nucleic acid gel electrophoresis to track DNA front in agarose gels. Typically runs at 50bp in up to 2.5% agarose.

Application

Orange G has been used as a DNA gel loading dye.[3][4][5]

Orange G is a tracking dye used in nucleic acid electrophoresis to track DNA front in agarose gels. Also used in SDS-capillary electrophoresis as a standard. Typically runs at 50bp in up to 2.5% agarose.
