Hi Yoshiki
        I've used pRc/CMV but not for lacZ expression.  I think it should work
OK. Invitrogen have a
new expression vector out called pcDNA3 which allows expression in COS and
other eukaryotic cells.  The send it along with a plasmid containing the CAT
gene put in to the Hind III site.  I've tried this in COS cells and it works
fine, I guess I should try in my CHO cells to see how it is in these.  To assay
the CAT gene I use an ELISA I bought from Boerhinger Mannheim, and it worked
well first time :-)
	BTW I don't work for any of these companies or any profit making
organization come to that, I'm not sure what the organization  I work
 for is really doing :-)
