Hi, Don

We used to performe PCR from cells contained in the saliva for RFLP analysis 
some years ago. Probably there are better protocols availbale now. The 
protocol is very easy: your try to wash the cells (actually NOT really easy) 
in PBS. The cell pellet (from 2 ml saliva we obtained about 20 µl pellet) was 
then cooked with approx. 2 times (or more) of the pellet volume of essentially 
Promega 10x Taq-polymerase buffer (containing 1% Triton X-100)for e.g. 10 min. 
Then You set up your PCR by simply diluting this soupe 1:10. I cannot say 
whetherthe cells can stand US postal service. In addition, we finally stopped 
this procedure because of the high possibility of contaminations and 
uninterpretable results we got.

hope it helps
