Agilent Technologies, Protein Discovery Announce Exclusive Agreement for Worldwide Distribution of PPS Silent® Surfactant

SANTA CLARA, California, AND KNOXVILLE, Tennessee- February 10, 2009—Agilent Technologies (NYSE: A) and Protein Discovery Inc. today announced their distribution agreement for PPS Silent Surfactant, a specialized reagent from Protein Discovery used to prepare biological samples for mass spectrometry analysis. The exclusive agreement encompasses aspects of sales, marketing and support for PPS Silent Surfactant.

PPS Silent Surfactant is an acid-cleavable, zwitterionic detergent that helps researchers produce high-quality mass spectra from biological samples. The patented reagent is particularly useful for solubilizing hydrophobic proteins for extraction and preparative digestion.

“PPS Silent Surfactant is a powerful addition to Agilent’s sample-preparation product offering and improves the customer experience and capability for LC/MS-based research,” said Bill Molnar, Agilent vice president and general manager, Genomics and Bioreagents. “It can be used at any stage of the mass spec sample-preparation process without interfering with separation mechanisms, ESI or detection. It relieves detergent interference problems and improves recovery and identification of more proteins. These advantages enable researchers to produce better data and get even greater satisfaction from the other product elements of our comprehensive mass spectrometry portfolio.”

“This agreement represents a significant milestone in Protein Discovery’s commercialization of specialty products for preparative proteomics,” said Chuck Witkowski, president and chief executive officer of Protein Discovery. “Agilent’s status as an innovator in sample preparation, combined with its extensive global distribution network, make Agilent a great partner for Protein Discovery.”

Effective immediately, Agilent customers can place orders for PPS Silent Surfactant through Agilent’s Life Sciences and Chemical Analysis division at
