No, RT-PCR measures RNA levels. For secreted cytokines I believe
the "conventional" methods are based upon sandwich ELISA.
A company called Cytimmune Sciences visited recently and were pushing
an alternative to the sandwich method which was based on competetion
using biotinylated cytokines. I guess there are plenty more systems out
