1500 V, 50 mA, after about 10 min the gel was pulled off from the top of the plates
into the upper reservoir. When I repeated and pre-ran gel at 500 V, this did not
occur; however, when I increased a voltage, it was pulled again. I never
experienced it with 20% gels (with 8M urea, in both cases). What might be a
Thanks for explanations!
