Abstract
Laboratory automation has the ability to increase the throughput and efficiency of laboratory processes to keep pace with current backlogs and requests for analysis. This paper addresses the specific studies employed to properly evaluate an automated method for DNA quantitation setup using Applied Biosystems Quantifiler Human DNA Quantification kit on a Biomek 3000. The calibration of robotic pipetting as well as comparison with manually performed steps confirmed the accuracy of the automated methods used. Reproducibility studies evaluated differences between robotic and manually prepared human DNA standard curves. Additional studies examined DNA samples of known quantities, extract storage formats, sensitivity, and an assessment of contamination. The Biomek 3000 not only demonstrated reproducibility and accuracy that equaled or surpassed the manual method but also revealed a contamination-free method to replace the multiple pipetting steps required during quantitation setup.
