Some questions about Polyacrylamide gels

[David L Haviland]

Just my $0.02 worth, we had people in the lab that were sensitive to 
butanol, so in a pinch until these people left the lab, we simply use 
distilled water to overlay the gels.   More care must be taken with 
water than butanol as the water, if forcefully added to the gel,  can 
dilute the top part.   But if applied with care, it works just as well.

If everything seems to be going so well, you have obviously 
overlooked something.
