Another way to go is to use a so-called bicistronic vector:
Promoter-MCS-IRES-Marker-PolyA. IRES (internal ribosomal entry site,
usually EMCV) direct translation of the marker, so that all the cells
tat express the marker also express the MCS-inserted gene. There is a
number of such vectors around, so if you need further information just
drop me a note...
