It happens every day in many laboratories; qPCR data cannot be reproduced, sequenced peaks prove to be artifacts, or the 96-well plate enzyme assay has to be repeated due to a pipetting error. In the long term, this results in significant expense. However, most of these costly events can be avoided if pipetting is understood as a holistic process with several components.
GPP (Good Pipetting Practice) presents a comprehensive and systematic approach to optimizing pipetting accuracy and repeatability.
