Punch tool cleaning protocol
Pull the punch tool apart.
Dip both the rod and the column briefly into solutions of 10% bleach, distilled water, followed by second bath of distilled water, and a fourth bath of 95% ethanol. Ethanol is preferred as it dries much faster. Strong detergents should also be avoided.
Blot with a Kim wipe and allow to dry for 10 min. Note that the ethanol can go up inside the column of the punch tool, so it is best to blot until all liquid is gone. It is also important that the punch tool is completely dry before punching out another DNA spot, as the alcohol will effect the transformation efficiency.
