I suppose you already have cells resistant against G418 resp. your
antibiotic of choice.
Then trypsinize them and seed them at a (theoretical) concentration of 1 to
3 cells per well in 96well microplate. After a few days, you should see
growing foci. Test those wells where only one focus is present for your
transgene and expand them in 12 or 6 wells.
Store the surplus cells from the first step in nitrogen for backup
purposes. 1 or 2 microplates usually are sufficient.
This method IMHO is much efficient than using cloning cylinders or whatever.
