Methods was indeed depending having (i) blood fractionation and shipping to your dos-D club coded cryo hoses, (ii) DNA isolation and you may normalization and you can (iii) shop and you may recovery of just one billion DNA products working in the ?20°C. Products are also kept from the ?80°C into the guide super-freezers plus the new vapour stage from liquid nitrogen. Details might possibly be discussed from inside the a different report (K Hveem, private telecommunications, ).
