Application Note: Elimination of Amplifiable Nucleic-Acid Carryover from Fixed Tips on an Automated Liquid Handler in a Forensic DNA Laboratory
3 March 2008

For forensic evidence to be useful in the criminal justice system, there must be no question of sample cross-contamination. This application note presents experiments performed by the Research and Development group affiliated with the National DNA Databank of the RCMP to demonstrate that amplifiable material may be effectively removed from fixed, washable tips on an automated liquid handler with a protocol of flushing, exposure to bleach solution and washing.
