Automated DNA-processing The second Tecan robotic workstation Genesis Freedom 200 combined with the Tecan GENios detection system automatically measures the extracted DNA from the cell culture samples and normalizes the DNAconcentration ready for genetic analysis by the project’s collaborators (Fig 4). The extracted DNA samples are usually at a wide range of concentrations depending on the state of the sample from which DNA was extracted. The Tecan GENios™ microplate reader measures the DNA-concentration and the Freedom workstation then automatically dilutes the DNA to the target concentration. This ensures that the optimal conditions for subsequent genetic analysis are met. The workstation generates multiple sealed daughter plates ready for analysis. The system also features a “pick and place” arm capable of cherry picking minitubes with the extracted DNA from closely packed 96-position racks (Fig 5).

The Children of the 90’s project: genetic and non-genetic influences The Children of the 90’s project is known to the scientific community as the Avon Longitudinal Study of Parents and Children (ALSPAC). This unique project is based at the University of Bristol. It is discovering new ways of understanding diseases with a view to improving prevention and treatment and has created the world’s largest biological sample collection to support these aims.

important new phase for the Children of the 90’s project. Working out the interplay between genetic and non-genetic influences on the growth and development of normal children from the womb into adult life is the key to understanding, and therefore preventing or treating, common diseases. The new robotic workstations from Tecan are critical aids in achieving this goal.

Around 14,000 children and mothers have donated more than half a million samples to the project since 1991. No other study in the world has such a large DNA collection from a normal population. The project is mapping many aspects of the life of its children through to adulthood. The aim is to understand the ways in which the physical and social environment interacts over time with genetically inherited attributes to affect the child’s health, behavior and development. By understanding the causal pathways to diseases and disorders, preventive interventions can be devised for the future. As part of the program, cell samples are held in long-term storage for future study. One interim research finding has identified possible risk factors for peanut allergy in children. The great majority of children (84%) with peanut allergy had been exposed to creams containing peanut oil in the first 6 months of life. Another project is studying the causes of autistic disorders. Scientists will now be able to track the development of this mental disease and undertake groundbreaking research into both genetic and non-genetic factors underlying this condition. Tecans’ robotic workstations were given names in a competition with the children taking part in the study. After many suggestions two children named the Tecan Genesis Freedom 150-Plattform “Germinator” and the Freedom 200 “Robobanker”. The children started the machines on the official opening of the laboratory of the project in 2003 (see Fig 6). More information about the project is available at www.alspac.bris.ac.uk.

Fully automated purification of genomic DNA from large-volume blood samples1

High quality purified genomic DNA is essential for a wide range of molecular biology methods in genotyping. A new fully automated platform co-developed by Promega and Tecan provides the ideal solution for purifying genomic DNA from large-volume, whole blood samples (3-10 ml). The system combines Tecan’s Freedom EVO® platform with Promega’s MagneSil® DNA Large Volume Genomic DNA purification protocol. Genomic DNA can be purified directly from fresh, refrigerated or frozen whole blood samples using this simple, flexible, and scalable procedure. The genomic DNA is then ready for a variety of downstream applications. The complete integrated system is designed to allow on-the-fly batch size and automated reagent scaling depending on sample volume. The method of purification eliminates centrifugation and avoids problems found with conventional methods, such as reduced yields due to storage conditions, and lengthy times to resuspend the DNA into solution. 1 Disclaimer: Tecan’s Freedom EVO platform combined with the new Promega MagneSil Blood Genomic DNA, Large Volume system has been developed for research laboratory use only.

Columbus Pro™ – the high performance microplate washer Columbus Pro is a new microplate washer with excellent wash performance and unique process control options. The washer sets a new standard of reliability through a unique, 100% leak proof high-end aspiration pump with magnetic drive technology. Columbus Pro achieves very low residual volumes of less than 2 µl through multiple aspiration points for each well. Columbus Pro is equipped with an advanced overflow wash procedure. Overflow washing creates a circular flow of liquid in each well, providing high wash efficiency without compromising throughput by tedious sequential aspiration and dispense steps. The washer can be used stand-alone as well as integrated into Tecan EIA-platforms such as Freedom EVOlyzer®. The washer allows easy operation via a built-in keypad or the new WinWash™ Clinical software that fulfils the requirements for electronic records and signatures. The Columbus Pro for Enzyme Immuno Assays (EIA) in 96-well format complies with EU Directive 98/79/EC for in vitro diagnostic products.

A New Generic Luminescent Protein Kinase Assay Suitable For High Throughput Screening Lee Walker, Cambrex Bio Science Nottingham Ltd., Nottingham, United Kingdom Signal indicates drop in free ATP During a kinase reaction, the level of free ATP in the reaction mixture decreases as the γ-phosphate is transferred from the ATP molecule to the kinase substrate. This drop in free ATP can be accurately measured using the patented bioluminescent kinase reagents from Cambrex. The bioluminescent reaction is catalyzed by the firefly luciferase enzyme1 and provides speed, sensitivity and convenience. The reagent contains luciferin and luciferase, which emits a stable light signal, with an intensity proportional to the concentration of ATP.

An assay with a four-step procedure Cambrex kinase assay reagents were used to test p38 phosphorylation of the myelin basic protein substrate and p38 inhibition using Figure. 1: The new protein kinase assay is based on a glow luminescence signal, which is detected using the luminescence mode of Tecan's ULTRA Evolution™ multifunctional detection reader.

Results comparable with conventional assays Using the kinase SAPK2 (p38) and myelin basic protein substrate as a model, the usefulness of using Cambrex kinase reagents to measure kinase activity and inhibition with Tecan’s Ultra Evolution has been demonstrated. This method is very simple to develop and run and can potentially be applied to any ATP-dependent protein kinase and target substrate. The assay has been proven to be robust with Z-values greater than 0.8 exhibited and reproducible and sensitive enough to determine low potency inhibition (Fig 2).

Tecan Opens New Application Development Center in Kobe, Japan

The new Tecan Kobe Application Development Center is located inside the Kobe International Business Center (KIBC).

Tecan officially opened its new Application Development Center in Japan on October 1st 2004. The new facility is situated in Japan’s rapidly growing center for cell research and medical industry development in Kobe. It provides the ideal environment to further develop the well-known flexibility and adaptability of Tecan’s products and automation solutions. By building up a collaborative network with academia and biotech companies, Tecan Japan will offer better support and resources for all life sciences customers. The facility is used to showcase new laboratory automation solutions based on the company’s Freedom EVO® liquid handling workstations as well as a range of plate readers and washers. The center also provides a location to continuously develop Tecan’s products by optimizing protocols and gathering data that validate new solutions. This will ensure new reliable protocols with minimum set up time and ultimate performance for customers. “Over the past two years we received many new automation ideas from our customers that we wanted to pursue. However due to limited facilities we could only work on a few of the ideas, as it required many experiments to validate their protocols,” said Scott Eaton, President of Tecan Japan. “Now, with this new facility, our staff has an ideal setting to test and validate the majority of our customers’ ideas.” The opening was celebrated with a ceremony that was held on October 5th 2004 at the Kobe International Business Center (KIBC). The ceremony commenced with a keynote speech describing the objectives of the center. Scientific luminaries in cell research, as well as pharmaceutical sciences, gave congratulatory speeches. After the ceremony, the attending dignitaries and invited researchers were given a tour of the lab and a brief explanation of the current solutions under development. These range from automated physical chemistry property measurements to cell-based assay optimization and cell culture solutions.

Concentrated power

The Genesis FE500 performs all the steps needed to prepare samples for analysis, including pre-sorting, centrifugation, barcode labeling, volume check (tube inspection unit sees through barcode labels), decapping, aliquoting and destination sorting into analyzer racks. In fact, it offers all the capabilities of larger, more complicated preanalytic installations, but concentrated into a compact, easy-to-use system. And its ability to handle a variety of tubes and tube-racks from a range of manufacturers gives you the power to choose the analyzer you want to work with.
