Definiens has released Proteomweaver 2.1. Definiens said the updated version of its 2D gel electrophoresis analysis software uses a new quantification algorithm that is designed for multi-fluorescence gels and can detect protein expression ratios as low as 1.17 with a significance of 0.001 using two replicate gels.
SimBioSys has launched a new ligand docking and virtual screening program called eHiTS (electronic High Throughput Screening). Typical docking speed per ligand per CPU is a few seconds, according to the company, and the software supports parallel execution via SMP, Linux clusters, or distributed grid computing. eHiTS is currently available on Unix platforms. Further information is available at http://www.simbiosys.ca/.
