Physical question is actually gathered in the fitness examination station and you can transported each and every day because of the courier into biobank. Blood sampling adopted a rigid quality process, gathering serum, plasma, buffy coat, immortalized tissue to possess cellphone line development, certified tubes for trace material/issue analysis and you will RNA hoses. Pee is actually collected whenever possible, and frozen immediately. Measures was basically founded to own (i) bloodstream fractionation and shipments on dos-D bar coded cryo hoses, (ii) DNA separation and you can normalization and you will (iii) sites and retrieval of 1 million DNA trials performing during the ?20°C. Samples are also kept at ?80°C inside the manual super-freezers and in new vapour phase from water nitrogen. Information might be described in an alternate papers (K Hveem, private interaction, ).
