A new STR typing strategy has been developed allowing the simultaneous amplification and subsequent analysis of 11 polymorphic systems with amplicon sizes smaller than 270 bp. The multiplex amplification reaction includes six STR loci from the European standard set of loci (ESS) for DNA databases (D3S1358, D8S1179, D21S11, THO1, FGA and VWA) as well as four additional STR systems selected for their robustness (D2S1338, D12S391, TPOX and D5S818) together with the sex-specific locus amelogenin. After PCR amplification, the multiplex reaction is splitted into two sets of STR multiplexes by using biotin labelled primers only for one set. Using streptavidin-coated Sepharose beads five STR systems are separated from the other six systems prior to being analysed in two different runs on a capillary gel electrophoresis instrument. The multiplex system was developed and tested especially for the use in forensic casework if only limited amounts or highly degraded DNA is available, for instance, when isolated from telogen hair roots.
