Product Details

Investigator IDplex Plus Kit is a multiplex STR assay for human identification covering the 13 CODIS (Combined DNA Index System) core loci, D2S1338, D19S433 and Amelogenin.

The kits utilize our fast-cycling technology, enabling amplification in ca. 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.

Investigator IDplex Kit meets ISO 18385 requirements.

Performance

Investigator IDplex Kit utilize fast-cycling technology to provide reliable results in STR assays in ca. 90 minutes from extracted DNA.

The Fast Reaction Mix is based on proven QIAGEN multiplex PCR technology that has been 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 reliable, high-quality results from casework samples.

The Investigator IDplex Kit is validated and evaluated using the GeneAmp 9700 thermal cycler and the Applied Biosystems 3500 Genetic Analyzer.

The recommended amount of DNA under standard conditions for use with the Investigator IDplex Plus Kit 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.

Principle

Investigator IDplex 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 reduce overlap of loci alleles, thereby minimizing the likelihood of misinterpretation.

Procedure

The 15 polymorphic autosomal 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".

Investigator IDplex Plus Kit dyes and corresponding markers
Dye	Marker
6-FAM	Amelogenin	TH01	D3S1358	vWA	D21S11
BTG	TPOX	D7S820	D19S433	D5S818	D2S1338
BTY	D16S539	CSF1PO	D13S317	FGA
BTR	D18S51	D8S1179

The amplified loci then undergo capillary electrophoresis. The results can be analyzed using dedicated software, such as GeneMapper ID-X. See the table "Technical specifications" for more information.

Applications

Investigator IDplex Plus Kits are for rapid and reliable generation of DNA profiles from blood, buccal swabs and forensic stains or reference samples and are highly suited for:

Criminal database, forensic reference or casework samples
Paternity testing
Population genetics studies
Other human identity testing applications

FAQ

We recommend first adding master mix to the PCR plate and then adding the punch to avoid punches getting lost or mixed up due to electrostatic effects. Furthermore, we strongly recommend spinning down the PCR plate after setup to ensure all punches get fully submerged.

FAQ ID -3096

Yes. The protocol is generic and has successfully been tested on various commonly used instruments.

FAQ ID -3089

Amplification of Control DNA 9948 is appropriate as a PCR performance check. However, if you have access to reference samples at constant quality (for example, swabs or FTA donated by lab personnel), these samples may be used as additional in process controls.

FAQ ID -3094

No. Up to 2 µl can be added on top of a 25 µl reaction.

FAQ ID -3088

We do not recommend using more than one punch of 1.2 mm diameter for blood or buccal cells on FTA, or 2 µl of a crude buccal swab lysate. To adapt protocols to the type and quality of samples used in your laboratory, and to the CE instrumentation in use, adjust PCR cycle numbers and CE injection conditions.

FAQ ID -3090

Yes. Use of indicator cards helps to ensure sample is taken from an appropriate area of the FTA card. This may significantly improve success rates compared to procedures using non-indicator cards.

FAQ ID -3095

No. Amplification products of marker FGA have a slightly different size between IDplex Plus and IDplex GO! kits due to a change in the fluorescent dye linker used. Use of the IDplex Plus ladder will frequently cause off ladder calls for FGA alleles.

FAQ ID -3093

Yes. The Fast Reaction Mix contains Taq enzyme, Mg²⁺, and dNTPs in a pre-optimized concentration. Only IDplex GO! Primer Mix and sample needs to be added.

FAQ ID -3087

Yes. Sample materials used for direct amplification vary with regard to quality and quantity of DNA present, depending on sampling materials, procedures, and storage conditions. In order to obtain the highest possible success rates in routine use, it is essential to run a representative batch of samples for evaluation of optimal conditions. Furthermore, we recommend revisiting this aspect after a certain period of routine use to ensure the evaluated conditions are optimal and re-adjust if necessary.

FAQ ID -3091

The BT5 matrix standard is designed for use with our Investigator STR and Dipplex Assays. We do not disclose the containing dyes.

FAQ ID - 3364

No, primer site locations of markers have not been changed. Two additional SNP primers have been added to allow balanced amplification of vWA and D16S539 alleles carrying known primer binding site mutations. The mutations covered were observed in concordance studies in samples of African origin at an elevated level. The labelled FGA forward primer has been slightly changed with regard to the linker of the fluorescent dye. The change does not affect PCR amplification, but causes a slight size shift during capillary electrophoresis. The allelic ladder therefore has been changed accordingly.
