smells like a buffer problem to me.  are you certain that the buffer in the
gel is identical to that in the buffer wells?  ionic strength and all that?

be careful when using commercially-prepared gel premixes, as i have heard
horror stories of inconsistent batches, buffer screwups and the like.

i warm my gels without a comb; just before loading i rinse out the top,
insert the comb, load and run.
