Abstract: | 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™. 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. Choice of a polymerase tolerant of tissue residues and cycles of amplification appropriate for the amount of template expected yielded useful profiles with a custom-designed quintuplex primer set suitable for use with the Bioanalyser™. Samples stored on wires remained amplifiable for months, allowing their transportation unrefrigerated from remote locations to a laboratory for analysis using AmpFlSTR® Profiler Plus® without further processing. The field system meets the requirements for discrimination of samples from small sets and retains access to full STR profiling when required. |
