We have been using the FluoReporter kit from Molecular Probes part
number F-1930 (50 test kit). We find it works pretty well. No fixation is
required and the cells can easily be sorted and even grown. Transfected
cells are usually about a log up from the control or untransfected cells.
You must however keep the sample cold as untransfected cells quite rapidly
convert the substrate at room temperature. We havn't co-labelled with
antibodies but I don't see why this should be a problem.

Good luck
