Bottom line at this point is that the milkiness (actually it's more like
opalescence) apparently causes no problems with running or resolution.
Neither the water, nor the pH, nor the 10X TBE stock, nor the TEMED appeared
to be the cause. It's just as opalescent with 1x TBE, and the pH is right.
Only the amm. per. remains as a possible culprit. I'll probably switch that,
too, eventually, since PAGE gels really ought to be transparent, in my book.
