Primers Materials:tube with dried primer. On the tube label, you can see how many nmoles there are inside.   Experiment: Stock solution (100 µM): Spin the tube a few seconds.Open carefully and add 10 x (nmoles of primer) µl of autoclaved distilled waterRehydrate for 2 min (ie. leave on bench).Tap the tube.  Working solution (20 µM): 20 µl 100 µM stock solution80 µl autoclaved distilled water
