Precipitation in PCR Product (PERT Assay)

I am doing a coupled product enhanced reverse transcriptase assay (to
detect for rt activity in virus-amplified avian cell culture
supernatant). My PCR products contained a whitish precipitate (which
went back into solution with pipetting), and I had very faint bands on
the gel. Can anyone offer any explanation for the precipitate?
