D'oh!  I should have realized when you were talking about pellets!

Yes, 'Generations' comes off the column in solution, but 'Puregene' is a
precipitation.  Any gunk carry-through in Puregene (salting-out, isn't
it?) probably arises from red blood cell lysis.

It's (Generations) fine for PCR of small loci, but I wouldn't want to use
it for much else.  YMMV of course.
