I'm not clear on what kind of tubes you'll be using to collect the
blood. In my experience, you can get a good DNA yield (as well as
viable lymphocytes for culture) from blood collected in ACP solution B
(yellow top) for at least a week after collection. The lab next door
uses these tubes to collect blood in the Caribbean and bring it back
to process in Miami without refrigerating. I can ask for you exactly
how they store it and what is the longest they have kept a tube and
still managed to get DNA. Let me know if you need the info.
