Attention all the users out there that have seen Resolution problems at
200-250 base pairs.
We have been seeing this phenomenon on and off for a while now, although
tracing the absolute cause has been evasive. Like other users, we have
felt that plate cleanliness is a critical part of the problem.
We are using a TBE based system with formamide to denature the samples. 
Has this problem been seen with a different buffer and/or when urea is
used to denature the samples?
Any help would be really welcome!!
