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.
To put the gel medium on, get your print printed on the mat or unfinished canvas, and make sure it has dried at least 24 hours after printing before doing anything to it. Then apply your gel medium. You can also apply a coat of diluted acrylic medium before applying your gel medium.
