Collecting Sample Weight Data on Various Liquid Handling Robots

Effect of various sample-handling conditions on radioassay results.

Samples brought to the laboratory for routine radioassay often have been under suboptimal conditions. We compared the effect of some sample-handling conditions on the values for T3, T3 resin uptake (T3RU), T4, thyrotropin, cortisol, and prolactin in serum as determined by radioassays. Blood was collected in three separateplain red-top Vacutainer Tubes from each of six subjects. Serum was separa...

High-throughput transformation of Saccharomyces cerevisiae using liquid handling robots

Saccharomyces cerevisiae (budding yeast) is a powerful eukaryotic model organism ideally suited to high-throughput genetic analyses, which time and again has yielded insights that further our understanding of cell biology processes conserved in humans. Lithium Acetate (LiAc) transformation of yeast with DNA for the purposes of exogenous protein expression (e.g., plasmids) or genome mutation (e....

Liquid handling: dispensing reliability.

A Collaborative Approach to Collecting Data on Children’s Oral Health and Weight Status, Georgia, 2005

Throughout life, maintaining good oral health and a healthful weight are important factors in ensuring a good quality of life and limiting risk for disease. However, in Georgia, surveillance systems have done little to monitor the oral health and weight status of children. To fill this gap in surveillance data, Georgia’s dental health staff and the nutrition and physical activity staff collabor...

Liquid-handling Lego robots and experiments for STEM education and research

Liquid-handling robots have many applications for biotechnology and the life sciences, with increasing impact on everyday life. While playful robotics such as Lego Mindstorms significantly support education initiatives in mechatronics and programming, equivalent connections to the life sciences do not currently exist. To close this gap, we developed Lego-based pipetting robots that reliably han...
