There are several different qualities of dig available on the market,
which dissolve differently. I used to dissolve dig from sigma at 1% in
isotonic tris buffer with heating to 60°C filter afterwards and store
the solution at 4°C for several weeks. Upon prolonged storage a
precipitate forms which I took as a sign to discard the solution an
prepare a new one.(Carefully, very toxic!!!)
