Investigator IDplex Plus Kit 是一种用于人类身份确定的多重 STR 检测试剂盒，涵盖 13 个 CODIS（DNA 联合索引系统）核心基因座、D2S1338、D19S433 和釉原蛋白基因。

该试剂盒利用我们的快速循环技术，可实现在大约 90 分钟内完成扩增。Investigator IDplex Plus Kit 具有高度灵敏度，可从痕量 DNA 中快速获得可靠的结果，适用于所有法医应用和亲子鉴定。基因分析仪使用 BT5 Matrix 进行校准。

Investigator IDplex Kit 符合 ISO 18385 要求。

绩效

Investigator IDplex Kit 利用快速循环技术进行 STR 检测，在大约 90 分钟内便可从提取的 DNA 中获得可靠的结果。

Fast Reaction Mix 基于久经考验的 QIAGEN 多重 PCR 技术，并对该技术进行优化，可以增强抑制物耐受性。在 6 种类型抑制物（腐殖酸、血红素、鞣酸、靛蓝胭脂红、钙和胶原蛋白）浓度增加的情况下测试的检测性能显示出高灵敏度和优异的抑制物耐受性。这使得能够从案件样本中获得可靠的高品质结果。

使用 GeneAmp 9700 热循环仪和 Applied Biosystems 3500 Genetic Analyzer 对 Investigator IDplex Kit 进行验证和评价。

在标准条件下，Investigator IDplex Plus Kit 的 DNA 推荐用量为 0.5 ng。内部验证已证实使用 0.2–2 ng DNA 可获得稳定、均衡的结果，使用 <0.1 ng DNA 可获得可靠的结果。

原理

Investigator IDplex Kit 使用 QIAGEN 的快速循环 PCR 技术同时对 13 个 CODIS（DNA 联合索引系统）核心基因座、D2S1338、D19S433 和釉原蛋白基因进行快速扩增。精心设计的引物减少了基因座等位基因的重叠，从而最大程度地减少了误读的可能性。

FAQ

Yes. The Fast Reaction Mix of the Investigator IDplex Plus Kit contains HotStarTaq Plus enzyme, Mg2+, and dNTPs in a pre-optimized concentration. Only Investigator IDplex Plus Primer Mix and template DNA need to be added. Nuclease-free Water should be added to complete the reaction volume.

FAQ ID -3008

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

Yes. The protocol of the Investigator IDplex Plus Kit is generic and has been successfully tested on various commonly used instruments.

FAQ ID -3009

15 µl input volume can be used with the Investigator IDplex Plus Kit.

FAQ ID -3014

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

If you are using an ABI PRISM 3100-Avant/3100 or 3130/3130xl Genetic Analyzer, please use Any5Dye, if available. If you are using the Applied Biosystems 3500/3500xL Genetic Analyzer, please use filter set AnyDye. Otherwise, filter set G5 should be used. If you are using an ABI PRISM 310 Genetic Analyzer, filter set G5 should be used.

FAQ ID -3017

No. Unlike some other QIAGEN STR products (e.g., the Investigator Argus Y-12 QS Kit) there is no QS quality sensor included in the Investigator IDplex Plus Kit.

FAQ ID -3011

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

The optimum sample DNA input range of the Investigator IDplex Plus Kit is between 200–500 pg. However, reliable results can be obtained with less than 100 pg. For higher amounts of input DNA, consider adjusting the PCR cycle number.

FAQ ID -3015

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

No, the primer site locations of the markers in the Investigator IDplex Plus Kit have not been changed. Only minor changes have been introduced for some markers, e.g., to improve A addition to the PCR products.

FAQ ID -3012

Matrix BT5 should be used with Investigator IDplex Plus Kit.

FAQ ID -3016

The BT5 matrix standard is designed for use with our 5-dye Investigator STR Assays. We do not disclose the containing dyes.

FAQ ID - 3364

Yes. For example, cycle numbers can be increased to 32 or 34 in order to obtain higher signals for very diluted samples. However, please note that this promotes the amplification of nonspecific products or amplification from spurious background DNA.

FAQ ID -3010

The Investigator IDplex Plus Kit contains Primer mix, Fast Reaction Mix, Control DNA allelic ladder IDplex Plus, DNA size standard 550 (BTO), and nuclease-free water.

FAQ ID -3013

The template files for the Investigator IDplex Plus Kit for various softwares and analyzers can be downloaded from the Resource tab on the product webpage.

FAQ ID -3019

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.
