Sexual assault samples provide valuable forensic information. However, these samples are among the most difficult to process. Learn how Promega products can make this process faster and more consistent.
Automated Differex™ System
The Differex™ System is the first and only system that allows a forensic laboratory to automate every step of differential extraction. Process up to 48 differential extractions in less than 5 hours, with less than 1 hour of hands-on time.
Manual Differex™ System
The Differex™ System extracts DNA from sexual assault samples easily and quickly. Recently, the manual Differex™ System protocol was improved for better separation of epithelial and sperm fractions.
Slicprep® 96 Device
This device allows simultaneous centrifugation of 96 samples and is designed so that both the proteinase K digestion or cell lysis and centrifugation can be performed in the same device.View Centrifuge Compatibility
A protocol for easy, efficient separation of epithelial and sperm DNA that reduces variability in results from one examiner to another, a problem common to other differential extraction methods.
This Tech Tips article describes the automated Differex™ protocol, which combines two automated methods and two reagent systems, the Differex™ and DNA IQ™ Systems, to perform differential extraction and DNA purification from sexual assault samples.
