Streszczenie
In forensic biology, trace recovery by lifting traces for DNA typing using adhesive mini-tapes, is an efficient complement to traditional recovery methods such as swabbing or cutting. Here we present real crime case success rates for DNA sampling using mini-tapes based on a large data-set. The major findings are an increase in DNA mixtures compared to using conventional trace recovery techniques such as cutting, but in general with a significantly lower degree of inhibited DNA extracts and a higher proportion of usable DNA results.
