Automated Protein Crystallization Accelerates the Study of Cellular Function Solving the three-dimensional (3D) structure of nuclear receptor proteins is crucial for understanding the processes that mediate the development of multicellular organisms and those that can lead to diseases including cancer The organization of higher eukaryotic genomes and the control of gene expression during embryonic development in both normal and pathological differentiation is the focus of the Institute for Genetics and Molecular and Cellular Biology (IGBMC) in Strasbourg (France). The nuclear receptors of hormones constitute the largest family of ligand regulated transcription factors. To understand how nuclear receptors work and are regulated, it is crucial to solve their 3D structure and correlate structure and function.

different assay times with and without Te-MO 96. The Te-MO 96 wash procedure was extended by a distilled water mixing step in order to avoid a contamination of the assay solvents with the 50%/50% EtOH/distilled water wash solution.
Conclusion The PAMPA PSR4p has been successfully implemented on a Genesis Workstation 150 with Te-MO 96. The correlation of the permeation constants shows that the assay quality has been maintained. In addition the assay time has been reduced by a factor of 2.6, increasing the sample throughput from 100 samples/week up to 260 samples/week (triplicate determination). The bottleneck of the assay is the acquisition of UV spectra using 96-well microplate readers with monochromator technology. Newly introduced readers with diode array detection could overcome this problem and could lead to a throughput of up to 550 samples/week

Hybridization Station available to meet the needs of smaller laboratories. The HS 400 can process up to four microarray slides, ideally designed for researchers who need to carry out a modest number of experiments per run. The fully automated workstation significantly improves the reproducibility and sensitivity of microarray results and is suitable for many applications in genomics, proteomics and drug discovery, including key applications such as gene expression profiling, gene regulation, pharmacogenomic studies, up to the validation of gene expression
HS 400’s big brother, the HS 4800 Hybridization Station, provides an automated solution for medium to high throughput hybridization with identical process performance and full protocol compatibility. Up to 12 microarray slides can be processed in parallel on the HS 4800 Master System. Through its modular design, the Master System may be easily combined with one, two or three Extension Units (12 additional slides per unit). This allows processing of up to 48 slides using up to four different protocols in parallel.

MipTec Tecan hosted workshop for automation and data management at this years MipTec in Basel The introduction of the newly launched joint offer of Tecan Workstations and IDBS’ ActivityBase data management software was supported by a seminar that Tecan and IDBS co-hosted at this years MipTec in Basel, May 12th-15th. This combined offer provides customers with a pre-configured automation of various assays, together with fully integrated software to record all data in real time. The comprehensive seminar, explaining both workstations and software was attended by 27 participants. “It’s impressive to see how well these Tecan workstations fit together with this powerful data management software”, commented one of the participants. “The system allows data collection of all processes on the workstation with just one software solution.” Further, visitors were able to see the new AutoLoader for Aquarius at the Tecan booth.

Freedom to evolve
Freedom EVO is a new robotic and software platform that enables the flexible integration of a range of powerful application tools. Whether you're involved in genomics, proteomics, drug discovery or clinical diagnostics, Freedom EVO with its Freedom EVOware software allows you to configure individually optimized modules into a fully integrated, robust system that exactly meets your application requirements. Freedom EVO can be readily reconfigured to evolve with your changing needs, thereby protecting your investment for many years. Freedom EVO may, for example, be upgraded with a Te-MO multi-channel pipetting option with 96- or 384-channel heads to increase its throughput. It supports up to 3 robotic arms which can be selected from a liquid handling arm, a robotic manipulator arm for moving microplates and other labware, a "pick and place" arm or a robotic manipulator arm with extended Z axis to reach devices beneath the worktable.
