We resolved that issue here at Research Genetics with a very low tech
solution. We add an additional 5 ul water to each plate depending on the
order of loading (1st plate = 10 ul, 2nd = 15ul, 3rd = 20 ul, 4=25 ul) Our
results have been quite nice with this scheme and we avoid dealing with
sticky plate seals.
