Press Release Summary: Thermo Fisher Scientific Inc., the world leader in serving
science, today announced the integration of Matrix Science\'s Mascot search engine
for protein identification with its BioWorks software. The SEQUEST search algorithm
from the University of Washington, (a component of BioWorks software) and Mascot are
the two most widely accepted search engines in the field for protein identification
and PTM characterization.



Press Release Body: Thermo Fisher Scientific Inc., the world leader in serving
science, today announced the integration of Matrix Science\'s Mascot search engine
for protein identification with its BioWorks software. The SEQUEST search algorithm
from the University of Washington, (a component of BioWorks software) and Mascot are
the two most widely accepted search engines in the field for protein identification
and PTM characterization.

This integration will enable users to consolidate identification results from the
two search engines and cross-validate the results, taking advantage of the
complementary information provided by each. Studies have shown that different search
engines match different spectra, resulting in a large overlap and some unique
protein identifications for each. Including both search engines in the same software
platform provides a new level of confidence in protein identification. The new
integration of SEQUEST and Mascot within the Thermo Scientific BioWorks platform
enables the kind of flexibility in mass spectrometry data interrogation that
customers are looking for.

John Cottrell of Matrix Science stated, \"We are delighted that Thermo Fisher
Scientific will enable its customers to purchase Mascot as part of a complete
instrument and software platform\". In addition, Andreas Hühmer, proteomics marketing
director at Thermo Fisher Scientific said, \"It\'s all about flexibility for our
customers - we want to give customers who have already chosen superior
instrumentation the choice to analyze their data with the search engine they prefer,
or to increase their protein coverage by combining the results from both.\"
Integration of Mascot provides users with comprehensive tools for data processing,
protein identification, quantitation and characterization.

About Matrix Science
Matrix Science develops and markets bioinformatics products and services for mass
spectrometry-based proteomics. Mass spectrometry has become established as the
method of choice for protein analysis, providing levels of speed and sensitivity
that cannot be matched by other techniques. Mascot, Matrix Science\'s lead software
package, searches mass spectrometry data against molecular sequence databases to
identify the constituent proteins and characterize post-translational modifications.
The search procedure is computationally intensive, requiring complex statistical
calculations to be performed rapidly while streaming through large protein and
nucleic acid sequence databases. The company is based in London, UK, and has offices
in Philadelphia, PA and Tokyo, Japan.
