The Quantifiler® Trio DNA Quantification Kit is a robust kit that enables forensic laboratories to simultaneously obtain a quantitative and qualitative assessment of total human and human male DNA in a single, highly sensitive real-time PCR reaction. This guides selection of the optimal short tandem repeat (STR) analysis chemistry (autosomal, Y-STR, or miniSTR) and streamlines the workflow while increasing downstream analysis success rates. The kit includes enhanced quantity and quality indicators that help deliver accurate, sensitive, and specific results that work together with the HID Real Time PCR Analysis Software v1.2 to enable informative and integrated workflow decisions. The Quantifiler® Trio kit and the HID v1.2 software are designed for use with the Applied Biosystems® 7500 Real-Time PCR System.

Highly Accurate
• Determines the ratio of human male to female DNA, even with minute male and excess female DNA (1:4000 or greater)

Highly Sensitive
• <1 pg/µL limit of detection. Quantifies DNA concentrations from 0.005 ng/uL to >50 ng/uL, enabling the use of a broad range of concentrations, with flexible protocols for higher concentration samples.

Highly Specific
• Detects human and higher primate DNA

Highly Informative
• Quantifies DNA from a wide variety of sources, including buccal swabs, blood, semen, tissue, and other human DNA sources, making this kit suitable for casework sample screening, databasing, and paternity labs
• Guides selection of the optimal AmpFLSTR® PCR Amplification Kit (autosomal, Y-STR, or miniSTR)
• Quality Index helps improve prediction of STR amplification performance and estimation of DNA quantity in degraded samples, especially in the presence of inhibitors.
• Enhanced inhibition detects the presence of PCR inhibitors (suggesting additional purification of extract and/or whether a mini STR kit like the MiniFiler™, NGM SElect™, or GlobalFiler™ kit may be necessary).

Highly Reliable
• Uses gold standard TaqMan® real-time PCR technology already widely adopted in forensic laboratories. Real-time PCR has the widest dynamic range of any DNA detection technology, allowing for more accurate quantification of low level samples.

Highly Efficient
• Dual quantification system minimizes sample consumption and streamlines workflow, with results in ~1 hour.
• Optimized and validated as part of a complete DNA testing system with the Applied Biosystems® 7500 Real-Time PCR System, AmpFLSTR® PCR Amplification kits, and HID Real Time PCR Analysis Software v 1.2 to enable high quality STR profiling results.

A Highly Informative Workflow Tool
The Quantifiler® Trio DNA Quantification Kit has been optimized and validated as part of a complete DNA testing system with the AmpFLSTR® PCR Amplification kits. The chemistry is compatible with commonly used extraction technologies for easy integration into current lab workflows. This enables the Quantifiler® Trio kit to function as a critical component of an improved and integrated workflow for more effective processing of forensic casework samples. Both the kit and the software are fully automatable with most liquid handling robotic platforms.

Comparison to Quantifiler® Duo Kits
There are several specific differences between the Quantifiler® Trio DNA Quantification Kit and the Quantifiler® Duo DNA Quantification Kit, including:
Target Loci: The Quantifiler® Trio kit uses multiple-copy target loci for improved detection sensitivity. There are three human-specific target loci: Small Autosomal, Large Autosomal, and a Y-chromosome target. Each consists of multiple copies dispersed on various autosomal chromosomes (Small Autosomal and Large Autosomal) or multiple copies on the Y-chromosome.
Optimized Chemistry: The assay chemistry has been optimized for more efficient multiplexing, faster PCR cycle times (~1 hour), and better inhibitor tolerance. The overall performance improvements allow the Quantifiler® Trio kit to better match the enhanced performance of newer STR kits that are designed to accommodate more challenging samples, like the Identifiler® Plus, NGM SElect™, or GlobalFiler™ PCR Amplification kits.
DNA Standard: The Quantifiler® Trio DNA Standard is a pooled, human genomic, smaller molecular weight DNA for improved stability, homogeneity, and correlation with forensic samples. There is a five point standard curve protocol that helps improve efficiency with up to 6% more samples on a plate.
Packaging Features: To help laboratories control for and minimize the potential of reagent contamination, as well as to better accommodate automated platforms, the Quantifiler® Trio DNA Quantification Kit has some key packaging features:
    --Four 100-reaction individual-use screw cap tubes (1 tube will process a 96 well plate)
    --The DNA standard is packaged in a separate box.
    --Both the reagent and DNA standard box are shipped together in an STR-style sleeve with peel & stick reagent lot barcode labels. This allows customers to separate out the reagents easily for special storage upon arrival at the laboratory.
For Forensic or Paternity Use Only.
