thermosequenase and ATP-p33.
We got some trouble in the loading surface after 2 hours run at 50oC,
that seemed to be uneven and irregular, making the second loading
Conditions used for the gel: 6% acrylamide, 8M urea, 1 X GTG buffer, 1

We also tried TEMED and APS 25%, 100 microlitres each, and the problem
Does anybody would have a suggestion to overcome those problems?
Please help me!
I would appreciate very much any sympathetic message.
