Bruker AXS Introduces New Ultra-Bright X-Ray Source for Protein Crystallography in the Laboratory.

ORLANDO, Fla. -- At Pittcon 2005, Bruker AXS, an operating company of Bruker BioSciences Corporation (NASDAQ: BRKR), today introduces a new highest-performance ultra-bright X-ray source, called MICROSTAR(TM)-H, for laboratory protein crystallography.

MICROSTAR-H is the culmination of Bruker AXS' long commitment to research on X-ray source technology in general, and so-called 'rotating anode generators' for protein crystallography in particular. It incorporates major advances in anode design, electron and X-ray optics to achieve extraordinary brightness and X-ray intensity, comparable to a typical 2nd generation synchrotron beam-line. Its advanced design also features operating and maintenance costs much lower than most conventional rotating anode X-ray sources.

The novel MICROSTAR-H also features exceptional positional and intensity stability. This unique combination of X-ray source intensity and stability allows many protein structures, that could previously only be determined at a synchrotron beam-line facility, to be solved quickly and easily in the home laboratory.

Roger Durst, Ph.D., Vice President of R&D and Global Crystallography Business Manager of Bruker AXS, commented: "Our customers are very excited about the capabilities of the MICROSTAR-H. This new ultra-bright X-ray source offers unprecedented performance, yet its cost of ownership and ease of use are superior to most other rotating anode sources. This makes the MICROSTAR-H an ideal tool for both high-throughput crystal screening as well as the most demanding structural proteomics studies, including SAD phasing and absolute structure determination."

Pittcon 2005, the 56th Pittsburgh Conference and Exposition on Analytical Chemistry and Applied Spectroscopy, is being held from February 27 through March 4 in the Orange County Convention Center. The product introduced here will be exhibited at the Bruker booth #3176.
