Wiil Glycerine, formaline, create problems for PCR

Dear Pandu, 

formaldehyde is likely to impair your polymerase activity. To my knowledge,
HCHO is used in some hot start applications. The result largely might
depend on final concentrations and the individual reaction conditions, also
the presence of HCHO alternative targets like albumin.
Glycerol will affect stringency. To be sure, better precipitate and wash
your DNA (your virus should be inactivated) or at least use a PCR buffer
that contains ammonium sulfate (might scavenge some HCHO).

Or just try and make some quality control.
