I'd thought of that, but I'll confess to not understanding the physics of a
blotting tank's electric field very well.  If you start placing non
conducting objects in the buffer tank, how much will that mess up the
uniformity of the electric field?  Obviously at some level it doesn't
matter, after all, the blots themselves are sandwiched in a sort of plastic
grid, but, what about when you start putting bigger objects in?  Anybody
