In our lab we have good experience with matings in
liquid culture, the efficiency is even higher in most cases.
You can do it with some cells taken directly from a plate,
suspended in 1 ml YPD and incubated for at least 3 hours
on a turning wheel. Our wildtype strain RS453 is known to
be a good mater. Problems could arise on microtiter wells
because of insufficient mixing.
