The Loading Dye * Loading dye is a colored buffer mixed with the DNA prior to loading onto the gel. The loading dye contains a relatively high concentration of either glycerol or sucrose. This makes the solution more dense than the surrounding running buffer so that when a sample is pipetted over top of a well it sinks down into the well.
Synthrapol is also commonly used as a surfactant to improve the penetration of water (and therefore dye) into the fiber, especially when dyeing wool.Other surfactants will also work. You can substitute one drop of liquid hand dishwashing detergent for this purpose.t is recommended to use Synthrapol when washing hand dyed fabrics before using them in a garment or quilt or when fabric is already quilted and bleeds onto adjacent fabric or simply to soak fabric before dyeing.
