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.
Soak the material to be dyed in the dye fixer solution. Let the fabric soak in the solution for 5 to 10 minutes, or until the fabric is completely saturated. You can reuse the fixer water and treat several batches of fabric in the same mixture. Step 4: Fold, Twist or Tie. Wring out excess fixer water back into the fixer water bucket. Place the âfixedâ fabric on dyeing surface and fold, twist or tie it into the pattern you want to dye. You can find instructions on common designs later in this guide.
