An easier method is to lay the plates flat on a support such as an
empty tip rack. The plates are held together by just two bulldog
clips, and no tape. Make sure the plates are horizontal, pour the
acrylamide in at the comb end and let the plates fill by capillary
action. If a bubble starts to form, just tap the plate just above
the forming bubble, but this is unneccessay if the plates are clean.
