GE Healthcare announced last week the release of its His GraviTrap 1 ml prepacked columns designed to purify histidine-tagged protein from clarified or unclarified samples without the need for a pump or purification system.
According to GE Healthcare, separations are completed in as little as 20 minutes using the His GraviTrap. The columns' protein binding capacity is approximately 40 mg per column. Purifications can be performed under either native or denaturing conditions using a wide rage of detergents, reducing agents and other additives.
The Max Planck Institute for Informatics has released DomainNetworkBuilder, a Cytoscape plug-in that decomposes protein networks into domain-domain interactions. According to the developers, the software transforms each protein node into a chain of consecutive domain nodes and constructs a putative network of interacting domain nodes. The plug-in is available at http://med.bioinf.mpi-sb.mpg.de/domainnet/index.html, and will also be available through the Cytoscape site at http://www.cytoscape.org/plugins2.php.
The Reactome project at Cold Spring Harbor Laboratory and the European Bioinformatics Institute has released Reactome version 15 at http://www.reactome.org. The release includes 1,463 total reactions and 1,095 annotated human proteins. New features include a module on the integration of energy metabolism, a revised data model to improve the handling of physical entities, and a new strategy for electronic inference of events in model organisms from curated human reactions.
