Alketbi on Trace DNA

Salem K Alketbi (Dubai Police - General Department of Forensic Science and Criminology) has posted An Evaluation of the Performance of Two Quantification Methods for Trace DNA Casework Samples (Journal of Forensic Sciences & Criminal Investigation, 16(5): 555950) on SSRN. Here is the abstract:
Trace or Touch DNA is one of the most common types of DNA samples found at crime scenes and is often collected in vast quantities from crime scene exhibits. Quantification methods that use real-time PCR (qPCR) technology are highly sensitive compared to traditional quantification methods, therefore, this study evaluated the performance of Quantifilerâ„¢ Human and Quantifilerâ„¢ Trio quantification kits for the same set of trace DNA samples collected from handled items recovered from crime scenes at the Biology and DNA Section of the General Department of Forensic Science and Criminology of Dubai Police Force. Both methods achieved comparable results indicating that there was no significant difference between the two quantification methods to quantify the collected trace DNA from the handled items (p > 0.05).
