Blood testing adopted a strict top quality process, collecting gel, plasma, buffy coat, immortalized muscle getting cell line development, specialized tubes to own shadow material/points research and you will RNA hoses. Pee is obtained if possible, and you may suspended instantly. Measures had been founded for (i) bloodstream fractionation and you can distribution into 2-D bar coded cryo hoses, (ii) DNA separation and you may normalization and you may (iii) shops and you can retrieval of just one mil DNA samples operating at ?20°C. Products are stored at the ?80°C into the guide super-freezers plus the brand new vapour ecuadorian dating stage away from h2o nitrogen. Facts might be revealed from inside the an alternative papers (K Hveem, personal correspondence, ).
