Best cell line for expression cloning but not COS-7 ?

Hi everybody,

I'm trying to clone a polymorphic gene present in 60% of humans by
expression cloning (i.e. transfection of pools of a cDNA library in a
eukaryotic cell line and then screening of the transfected cells for the
function of the unknown gene).

I tested COS-7 cells which are easely transfected but unfortunately they
already express the gene I'm looking for. I'm now looking for other cell
lines which could be used. They have to be easely transfected (by
electroporation or other) and grow well. Does anybody have a suggestion?

Thanks for your help
