Gel loading buffer is used as a tracking dye during electrophoresis. The dye has a slight negative charge and will migrate the same direction as DNA, allowing the user to monitor the progress of molecules moving through the gel. The rate of migration varies with gel composition. Store at 2-8℃ Composition 0.25% Bromophenol blue(w/v) 0.25% Xylene cyanol FF(w/v) 10 mM EDTA 1.0% SDS 50% Glycerol
