Transfection efficiency for CAT assays

[tsichlis at anaximander.rm.fccc.edu]

Dear netters,

I'm doing CAT assays in Jurkat and EL4 (T-lymphocyte) lines.  Transfection
is via electroporation (its not great but it works--if you have a method
you love please send it).
Recently I've started adding expression constructs to check activity on the
CAT reporters.  The problem is that they are also affecting the
CMV-betagalactosidase transfection efficiency control.
I thought about doing dot-blot quantitation of the CAT gene in Hirt
supernatants from the transfectants.  Is this a good idea?  Has anyone out
there thought of a better way to control for these assays?
