A rapid wire-based sampling method for DNA profiling.

This paper reports the results of a commission to develop a field deployable rapid short tandem repeat (STR)-based DNA profiling system to enable discrimination between tissues derived from a small number of individuals. Speed was achieved by truncation of sample preparation and field deployability by use of an Agilent 2100 Bioanalyser(TM). Human blood and tissues were stabbed with heated stainless steel wire and the resulting sample dehydrated with isopropanol prior to direct addition to a PCR.
