Automation of a Differential Digestion Protocol for Processing Sexual Assault Kits Using the VERSA Automated Liquid Handling Workstation
16 May 2017

Separation of sperm cell DNA from epithelial cell DNA in processing sexual assault kits remains a time-consuming, manual task, contributing to the backlog of evidence processing. This whitepaper describes a method for improving the efficiency of processing forensic samples by using the VERSA 1100 Automated Liquid Handling Workstation to automate the differential digestion process. The method didn’t compromise the quantity or quality of the DNA recovered and there was a six-fold decrease in sample processing time in comparison with the manual method.
