Press Release Summary: San Jose, CA., (July 17, 2008) - Thermo Fisher Scientific
Inc., the world leader in serving science, today announced that Harvard Medical
School (HMS) is using a range of its mass spectrometry instrumentation for
cutting-edge targeted proteomics applications. Scientists from North Carolina State
and Harvard Universities, along with John M. Asara Ph.D., director of the mass
spectrometry core facility at the Beth Israel Deaconess Medical Center (BIDMC), a
teaching hospital of Harvard Medical School, have used a Thermo Scientific LTQ
linear ion trap and LTQ Orbitrap XL to extract and sequence tiny pieces of collagen
protein from dinosaurs. The sequences from a 68 million-year old Tyrannosaurus Rex
and a 160,000 to 600,000 year old mastodon are the oldest to ever be reported. The
protein fragments were compared to peptide/protein sequences in existing databases,
leading the researchers to propose a link between the T. rex and current day
chickens and the mastodon with modern elephants. Recently the Harvard team has been
able to place the T. rex on the animal kingdom\'s phylogenetic tree using molecular
evidence.

Thermo Fisher Scientific Mass Spectrometry Instruments Used by Harvard University to
Identify Proteins in Dinosaur Fossils and Cancer Pathways

San Jose, CA., (July 17, 2008) - Thermo Fisher Scientific Inc., the world leader in
serving science, today announced that Harvard Medical School (HMS) is using a range
of its mass spectrometry instrumentation for cutting-edge targeted proteomics
applications. Scientists from North Carolina State and Harvard Universities, along
with John M. Asara Ph.D., director of the mass spectrometry core facility at the
Beth Israel Deaconess Medical Center (BIDMC), a teaching hospital of Harvard Medical
School, have used a Thermo Scientific LTQ linear ion trap and LTQ Orbitrap XL to
extract and sequence tiny pieces of collagen protein from dinosaurs. The sequences
from a 68 million-year old Tyrannosaurus Rex and a 160,000 to 600,000 year old
mastodon are the oldest to ever be reported. The protein fragments were compared to
peptide/protein sequences in existing databases, leading the researchers to propose
a link between the T. rex and current day chickens and the mastodon with modern
elephants. Recently the Harvard team has been able to place the T. rex on the animal
kingdom\'s phylogenetic tree using molecular evidence.

John Asara (who is also an instructor in pathology at HMS) and his colleagues at
BIDMC provide the Longwood Medical Area and other researchers with proteomics
services. They use mass spectrometry to develop proteomics-based strategies for
identifying novel signaling proteins and modifications of functional significance to
cancer pathways. The mass spectrometry techniques he has developed for sequencing
proteins in human tumors using the LTQ linear ion trap and LTQ Orbitrap XL have also
been applicable to his work on fossilomics (the analysis of fossil bone proteins
from extinct organisms).

Asara credits the Thermo Scientific instrumentation with providing the sensitivity,
ultra high mass accuracy and resolution required by these challenging applications.
\"The LTQ increased our throughput and depth of analyses,\" he said. \"Additionally,
the LTQ Orbitrap XL has done wonders for sorting out minor sequence discrepancies.
With the LTQ Orbitrap XL, all forms of proteomics analysis are possible from
qualitative analysis to quantitative analysis through stable isotope labeling, as
well as label-free methods.\"

Both Asara\'s cancer research and fossilomics analyses benefit from the advanced
Thermo Scientific MS technology. \"The two technological advances that stand out with
my current instrumentation are the linear trap with dual ejection to two different
multipliers, which substantially increases sensitivity and scan speed, as well as
the Orbitrap\'s capability for high resolution accurate mass measurements,\" Asara
said. \"Additionally the HCD collision cell on the LTQ Orbitrap XL allows for
extremely high MS/MS mass accuracy and resolution, in addition to acquiring very low
molecular weight fragment ions.\"
