Poster Information
Abstract: Crime scene investigators are trained to air-dry evidentiary samples following swab-based collection. Drying swabs can lead to irreversible binding of DNA to the swab material resulting in low DNA recovery. However this step can be challenging, especially in areas of high humidity and air moisture content. There are several factors affecting DNA integrity and yields of evidentiary samples:

Irreversible binding to swab material
Nucleases
Microbial contamination
Temperature fluctuations
Heat
Humidity
UV light
Improper collection
Storage conditions and length of backlog
Transport conditions & transit time

Mawi has developed iSWAB-ID, an efficient liquid-based sample collection system which utilizes swabs. iSWAB-ID enables long term room temperature stabilization of the collected sample at the point of collection while ensuring proper chain of custody. This system maximizes sample recovery and simplifies sample processing extensively over current practices, allowing for Enhanced ID Profiling.
