1. Description
STR (short tandem repeat) loci consist of short, repetitive sequence elements 3–7 base pairs in length (1–4). These
repeats are well distributed throughout the human genome and are a rich source of highly polymorphic markers,
which may be detected using the polymerase chain reaction (5–9). Alleles of STR loci are differentiated by the
number of copies of the repeat sequence contained within the amplied region and are distinguished from one
another using uorescence detection following electrophoretic separation.
The PowerPlex®ESI 17 Fast System(a,b) is used for human identication applications including forensic analysis,
relationship testing and research use. This system allows co-amplication and four-color uorescent detection of
seventeen loci (sixteen STR loci and Amelogenin), including D22S1045, D2S1338, D19S433, D3S1358, Amelogenin,
D2S441, D10S1248, D1S1656, D18S51, D16S539, D12S391, D21S11, vWA, TH01, SE33, FGA and D8S1179.
The PowerPlex®ESI 17 Fast System is designed with six of the original seven European Standard Set (ESS) loci
(D3S1358, D18S51, TH01, vWA, D8S1179 and the more common FGA alleles) along with D16S539 and D19S433 as
smaller amplicons (<250bp), while the loci recommended by the European Network of Forensic Science Institutes
(ENFSI) and European DNA Proling Group (EDNAP) (D1S1656, D2S441, D10S1248, D12S391 and D22S1045) are
present as larger amplicons. A complementary system, the PowerPlex® ESX 17 Fast System, amplies the same
seventeen loci present in the PowerPlex®ESI 17 Fast System but with the new ENFSI/EDNAP loci designed as
mini-STRs (<125bp; D2S441, D10S1248 and D22S1045) or midi-STRs (125–185bp; D1S1656 and D12S391).
Therefore, these two STR systems can be used to complement each other when analyzing degraded or challenging
samples to maximize recovery of allelic information from as many loci as possible and allow conrmation of results
obtained with the other system.
The PowerPlex®ESI 17 Fast System and all system components are manufactured in accordance with ISO
18385:2016. All necessary materials are provided to amplify STR regions of human genomic DNA, including a
hot-start thermostable DNA polymerase, which is a component of the PowerPlex®ESI/ESX Fast 5X Master Mix.
This manual contains a protocol for use of the PowerPlex®ESI 17 Fast System with the GeneAmp®PCR System
9700, Veriti®96-Well Thermal Cycler and ProFlex® PCR System in addition to protocols to separate amplied
products and detect separated material on the Applied Biosystems®3130, 3130xl, 3500 and 3500xL Genetic
Analyzers. Protocols to operate the uorescence-detection instruments should be obtained from the instrument
manufacturer. Amplication and detection instrumentation may vary. You may need to optimize protocols including
amount of template DNA, cycle number, injection conditions and loading volume for your laboratory instrumentation.
In-house validation should be performed.
