<p>Plasma aliquots and 3000 g supernatants were prepared from 30 individuals and assayed fresh (Thaw 1) or after an additional one (Thaw 2) or two (Thaw 3) freeze-thaw cycles. Correlation plots of mtDNA measurements (cycle threshold, x- and y-axes) are shown for plasma (left) or 3000 g supernatant (right). Spearman’s rho for each comparison is shown at bottom-right.</p
