Investigator Quantiplex HYres Kit
For detection and quantification of human and male DNA in forensic samples
- Simultaneous quantification of total human and male DNA
- Reliable results with sensitivity down to <1 pg/µl DNA
- PCR speed of 51 minutes on the Rotor-Gene Q
- Intergrated internal control to test for PCR amplification or inhibition
- Fully automatable reaction setup
The Investigator Quantiplex HYres Kit is a ready-to-use system for the detection and quantification of total human and male DNA using real-time PCR. Developed for superior sensitivity and reaction speed, it is designed to establish whether a sample contains sufficient DNA to enable DNA fingerprinting analysis (such as STR or DIP analysis) and whether there are inhibitors present. The Investigator Quantiplex HYres Kit provides reliable results independent of the subject"s gender or ethnic background.

Product Details
The validation of Investigator Quantiplex HYres Kit showed that it yielded robust and reproducible results within the normal range of conditions expected in forensic casework and human identity testing. The kit enables a significantly faster PCR than similar kits from other suppliers, yielding results in just 51 minutes on QIAGEN"s Rotor-Gene Q thermal cycler (see the figure "Excellent reaction time"). This enables a time- and cost-effective workflow.
The markers of the Investigator Quantiplex Kit has been validated and no copy-number variation has been detected between genders or across populations, making this marker an ideal real-time PCR target for DNA quantification (see the figure "No copy-number variation in the human target").
The kit can quantify a broad range of DNA amounts, from 50ng/µl to about 0.5pg/µl with a highly linear range between 20ng/µl and 4.9pg/μl of human genomic DNA. Furthermore, the assay provides sensitivity down to <1pg/μl(see the figure "Excellent sensitivity down to <1pg/μl").
Human identification is commonly based on the analysis of short tandem repeats (STRs), single nucleotide polymorphisms (SNPs), or deletion insertion polymorphisms (DIPs), depending on the demands of an examination or on the sample quality. These multiplex assays are complex systems that require a defined range of template input.
The Investigator Quantiplex HYres Kit contains reagents and a DNA polymerase for the specific amplification of two target regions and the direct detection of the specific PCR products on the Rotor-GeneQ real-time PCR cycler or Applied Biosystems 7500 Real-Time PCR Systems. The target for total human DNA is a 146bp autosomal multi-copy region of the human genome. This quantification target was selected in order to give high sensitivity with high reliability within different individuals and populations. It is detected using the green channel on the Rotor-GeneQ or the FAM dye channel on Applied Biosystems instruments.
The target region for male DNA quantification was selected in order to reliably give the same high sensitivity within different individuals and populations and in the presence of mixed DNA samples. This target region is detected as a 129bp fragment using the red channel on the Rotor-GeneQ or the Cy5dye channel on Applied Biosystems instruments.
In addition, the Investigator Quantiplex HYres Kit contains a balanced internal amplification control that is used to test successful amplification and identify the presence of PCR inhibitors. This heterologous amplification system is detected as a 200bp internal control (IC) in the yellow channel on the Rotor-GeneQ or in the VIC dye channel on Applied Biosystems instruments.
Detection of amplification is performed using Scorpions primers and a novel, fast PCR chemistry. Scorpions primers are bifunctional molecules containing a PCR primer covalently linked to a probe (see the figure "Scorpions primers and their function"). The fluorophore in this probe interacts with a quencher, also incorporated into the probe, which reduces fluorescence. During PCR, when the probe binds to the amplicon, the fluorophore and quencher become separated. This leads to an increase in fluorescence in the reaction tube.
The reaction chemistry was carefully optimized to further support the rapid mechanism. The novel PCR chemistry and enzyme, which were specifically developed for human and male DNA identification, enable high sensitivity and speed. Furthermore, the specially developed PCR chemistry contains the patent-pending additive Q-Bond, which significantly reduces denaturation, annealing, and extension times.
The kit is a ready-to-use system for the detection and quantification of human DNA using real-time PCR. See the table "Technical specifications" for more information. A set of template files has been developed to streamline the instrument setup and the analysis of the results on the Rotor-GeneQ (see table "Template files available for the Rotor-GeneQ").
