We've all done this at one time or another! Your error is common enough
to have been given a name:  "retrophoresis".  There is also "preparative
retrophoresis"  -- the name for extensive butanol extractions of the
upper buffer chamber to recover precious samples lost in this way.  Oh
well -- it least its a mistake you won't likely make again. Cheers.
