We pour our gels much the same way described, with one modification: I
used to have a really beautiful wooden T4 phage (made by an undergrad as
part of a project) in my lab.  One day I decided to take my gaze off my
screen to investigate the source of the incredibly annoying repetitive
tapping that seemed to have been going on for days, on and off - and found
my Honours students diligently banging their sequencing gel plates with
the head of my (now legless) phage, in order to remove bubbles.  Turns out
wood is sufficiently elastic that you can bang quite hard without
fracturing the plates, and bubbles were never a problem anymore (I never
had a problem BEFORE!).  It has now passed into routine method - I am
waiting for other labs to steal my phage (I wish they would), or build
their own.  Maybe we should SELL them - patent ProBoehAmPharm bubble
remover (Jim Graham, are you first in line?).
