An automated DNA profiling system based on the multiplex amplification of highly polymorphic short tandem repeat (STR) markers and the amelogenin locus was developed. Five STR loci with nonoverlapping allele size ranges have been utilized in the multiplex amplifications, including HUMD1S103, HUMTH01, HUMD21S11, HUMD18S51, and HUMFIBRA. One primer for each locus was labeled with a fluorescent dye (fluorescein) which allows detection on the single wavelength ALF DNA Sequencer (Pharmacia Biotech). As part of the detailed evaluation of the suitability of the hexaplex system for routine forensic use, the effect of variation in amplification parameters on the efficiency of the system was examined. Polymerase chain reaction amplification conditions were optimized to provide specific, robust amplification of forensic samples.
