Confidence in your evidence
When preparing for court, you need to have the utmost confidence in the evidence you are providing for a case. That’s why we’ve developed the Investigator Quality Sensor for our STR assays, an internal PCR amplification control for optimized, high-quality forensic workflow analysis. You can find the Quality Sensor in QIAGEN’s latest Investigator STR kits. The innovative Quality Sensor markers allow you to generate valuable data for your quality control and performance checks, without affecting PCR performance, even in the case of low DNA content samples. Using this internal control, you can identify inhibited samples, degraded DNA and failed amplification, allowing you to present your evidence in court with confidence.

In this practical webinar, learn how to use our innovative QS technology to get definitive, reliable STR results every time. See data from the developmental validation of our STR assay kits and the use of the QS to decide whether sample dilution leads to better results (i.e. inhibition) or not (i.e. degradation). -
Quality Sensors and interpretation: Database and casework samplesListen to Dr. Sheree Hughes-Stamm, an international thought leader in forensic analysis, as she explains how to use our Investigator Quantiplex Pro Kits, in conjunction with QS markers, to provide the most reliable results from both pristine and environmentally exposed samples. Discover how you can effectively tackle challenging forensic samples in less time.
