Stability and Persistence of Touch DNA for Forensic Analysis

Touch DNA is a potentially powerful sample type for forensic casework, but is challenging to work with due to low quantity, variable deposition amounts, and fundamental questions regarding stability over time. In this webinar we describe best-practices and initial results related to comprehensive studies of the stability of touch DNA after exposure to different environmental conditions.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on March 11, 2021.
