I haven't followed this discussion too close, and so I apologize if this
has already been suggested. Somewhere I heard it suggested that mineral
oil mixed with parafin wax would help soften it so that it would be easier
to remove the PCR rxn products later. Also, I'd heard someplace
(Biotechniques? PCR Meths Appl?) that Aldrich wax was substantially better
than other wax. Anyway, I tinkered around with mixing various proportions
of Aldrich wax with mineral oil. Personally, I found about 60-80% mineral
oil mixed with 40-20% wax to be preferrable.
But then again, I never thought of Vaseline !! :-)
