The method of Scheuermann, R.H. and S.R. Bauer (1993) Meth. Enzymol.
218:446-473 (quantitation of oncogene messages using RT-PCR, originally
done with 32-P labeled primers) has been done successfully using both
fluorescein-labeled primers and by post-staining gels with fluorescent 
intercalating dyes such as SYBR Green.  The gels were imaged on the 
Molecular Dynamics FluorImager. (disclaimer:  Sorry to advertise--I 
work for Molecular Dynamics.)
