I also had the same problem some time back and later found out as some
others have posted that this is due to ethanol/isoproponol in the
sample. Dry the pellet in a vacuum centrifuge (This will save your
sample being sucked out) completely and then dissolve it in buffer.
Also as another one pointed large amount of undigested high molecular
weight DNA may also cause this problem due to less density and the
problem is worse when trying to run High MW DNA just after
precipitation. Hope this will help you.
