Thermo Fisher Scientific Acquires Affinity BioReagents

Broad Range of Antibody Products Expands Thermo Fisher's Protein-Research Offering

Thermo Fisher Scientific Inc. (NYSE: TMO), the world leader in serving science, announced today that it has acquired Affinity BioReagents, a leading provider of antibodies, peptides, proteins and other reagents for life science research, based in Golden, Colorado.

"Affinity BioReagents is an ideal complement to our existing capabilities in protein research," said Marijn E. Dekkers, president and chief executive officer of Thermo Fisher Scientific. "This acquisition enhances our extensive antibody portfolio, which will drive growth as we combine these reagents with our current proteomics offerings to create end-to-end solutions for widely used protein-research applications." Such applications include Western blotting, ELISA, immunohistochemistry, flow cytometry and mass spectroscopy.

Affinity BioReagents has an offering of more than 35,000 reagents - primarily monoclonal and polyclonal antibodies - which are used in numerous fields of medical and academic research, as well as drug discovery. The company also provides recombinant proteins and custom antibody-production services. Affinity BioReagents had annual revenues of approximately $6 million in 2007, and will be integrated into Thermo Fisher's Analytical Technologies Segment.

Antibodies are proteins generated by the immune system in response to foreign substances, binding to them and flagging them for destruction. The ability of antibodies to bind with high specificity makes them ideal research reagents for isolating and identifying molecules of interest in cells. Antibodies have become an important tool for studying protein function in disease, including such key fields as immunology, neurobiology, toxicology and cancer research.
