The UniProt consortium consisting of the European Bioinformatics Institute, the Swiss Institute of Bioinformatics and the Protein Information Resource announced on Monday the launch of UniProt Release 2.5, a catalog of information on proteins. Monday. UniProt 2.5 consists of 1,559,136 entries. It can be accessed from the web at http://www.uniprot.org and downloaded from http://www.uniprot.org/database/download.shtml.
Thermo Electron has incorporated Highly-Selective Reaction Monitoring into its Finnigan TSQ Quantum family of triple quadrupole mass spectrometers. This analytical application will help to further eliminate chemical noise and generation of false positives, and will allow for lower detection limits.
By incorporating H-SRM, Thermo’s quadrupoles are capable of higher tolerance levels without any significant loss of ion transmission. While the less advanced Selective Readction Monitoring technique selects precursor ions with a mass tolerance of +/- 0.5 m/z or higher, H-SRM can select precursor ions with a mass tolerance of +/- 0.1 m/z or less.
The Blueprint Initiative research program announced the release of significant upgrades to its Biomolecular Interaction Network Database this week. The new BIND 3.5 is optimized for searching and data retrieval. It features a dynamic, collapsible HTML page that eliminates the use for pop-up windows, and an accelerated, simplified search process powered by the open-source Apache Jakarta Lucene project.
