Gary Siuzdak, Bruker Daltonics, Qiagen


Gary Siuzdak, author of Mass Spectrometry for Biotechnology, has released an updated book, The Expanding Role of Mass Spectrometry in Biotechnology. The book was printed by MCC Press and is for sale at

Bruker Daltonics released a new AutoFlex TOF/TOF system, a variation on its MALDI TOF/TOF mass spec, this week at the International Mass Spectrometry Conference in Edinburgh, Scotland. The system allows for fast, automated protein identification by mass fingerprinting as well as structural characterization by tandem MS in a compact size. The new system can be integrated into Bruker’s ClinProt system for biomarker discovery (see story p. 1). Bruker also released an updated model of its UltraFlex TOF/TOF system with improved mass accu-racy to 5 ppm for peptide mass fingerprinting and de novo peptide sequencing.

Qiagen has released a BioRobot Protein System for automated micro- to medium-scale purification of His-tagged proteins in a 96-well format. An integrated spectrophotometer adds a quantification step to the system. The system also comes with a pack of worktable accessories, software protocols, and purification chemistries.
