There are a number of methods in the literature. We are attempting to set up 
Q-PCR based on the method of Alard, P et al, (1993) BioTechniques 15, 730-737.
You might also want to look at Chevrier, D. et al (1993) Mol. and Cellular 
Probes, 7, 187-197, and Lehtovaara, P. et al (1993) 3, 169-175. Boehringer 
also sel kit/reagents to do this with their digoxygenin reagents.
