For multiplex amplification of 13 CODIS core loci, plus D2S1338, D19S433, and Amelogenin
PCR reaction speed of around 90 minutes
Highly sensitive and extremely inhibitor resistant
High-quality results due to improved signal-to-noise ratio
Straightforward protocols with ready-to-use Fast Reaction Mix
Simultaneous amplification of 16 loci
The Investigator IDplex Plus Kit is a multiplex application for human identification covering the 13 CODIS (Combined DNA Index System) core loci, D2S1338, D19S433, and Amelogenin. The kit utilizes QIAGEN's fast-cycling technology, enabling amplification in just 90 minutes. Highly sensitive with rapid and reliable results from trace DNA, the Investigator IDplex Plus Kit is suitable for all forensic applications and paternity testing. The genetic analyzer is calibrated with BT5 Matrix, an optimized dye technology.

The Investigator IDplex Plus Kit is intended for molecular biology applications in forensic, human identity, and paternity testing. This product is not intended for diagnosis, prevention, or treatment of a disease. This product is not available in all countries.
The Investigator IDplex Plus Kit utilizes fast-cycling technology to provide reliable results in approximately 90 minutes, which is significantly faster than kits from other suppliers.
The novel Fast Reaction Mix is based on proven QIAGEN multiplex PCR technology that has been further optimized to increase inhibitor tolerance. Assay performance tested in the presence of increasing concentrations of 6 types of inhibitor (humic acid, hematin, tannic acid, indigo carmine, calcium, and collagen) shows high sensitivity and superior inhibitor resistance. This enables the generation of reliable, high-quality results.
The Investigator IDplex Plus Kit was validated and evaluated using the GeneAmp 9700 thermal cycler (in standard mode) and the Applied Biosystems 3500 Genetic Analyzer.
The recommended amount of DNA under standard conditions is 0.5 ng. Internal validations demonstrated robust and balanced results with 0.2-2 ng DNA, and reliable results with <0.1 ng DNA.
The Investigator IDplex Plus Kit uses QIAGEN's fast-cycling PCR technology for the rapid, simultaneous amplification of the 13 CODIS (Combined DNA Index System) core loci, D2S1338, D19S433, and Amelogenin. Carefully designed primers prevent overlap of loci alleles, thereby minimizing the likelihood of misinterpretation.
The 15 polymorphic STR markers (D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, CSF1PO, FGA, TH01, TPOX, and vWA), and the gender-specific Amelogenin are amplified simultaneously in a single PCR and labeled with one of the dyes listed in the table "Investigator IDplex Plus Kit dyes and corresponding markers".
The amplified loci then undergo capillary electrophoresis. The results can be analyzed using dedicated software, such as QIAGEN's Investigator IDproof or IDproof Mixture Software. See the table "Technical specifications" for more information.
