CARLSBAD, Calif., and Research Triangle Park, NC — Oct. 13, 2008 — Invitrogen, Qualyst to Launch New Hepatocyte Screening Services and Products

Services, Products Combine CellzDirect Hepatocytes with Qualyst Patented B-CLEAR® Systerm

Carlsbad, Calif., and Research Triangle Park, NC, Oct. 13, 2008 – Invitrogen Corporation (NASDAQ:IVGN), a provider of essential life science technologies for research, production and diagnostics, and Qualyst, Inc., a leader in the development and commercialization of novel and proprietary hepatobiliary disposition and drug transport technologies, today announced the companies have entered a co-exclusive agreement to offer hepatocyte (liver cell) screening services and research products. Through Invitrogen’s wholly-owned subsidiary, CellzDirect, the company will provide in-house services and commercialized kits which combine Qualyst’s proprietary B-CLEAR® technology and CellzDirect’s industry-leading cell products. Financial details were not disclosed.

All new potential drugs require in vitro hepatocyte testing for toxicity risks. Determination of liver disposition and possible drug transporter interactions is a critical component of drug development. CellzDirect provides a complete line of hepatocytes, and high-quality products and services focused primarily on drug metabolism and transport. Qualyst’s B-CLEAR® technology is a patented system for the in vitro assessment and in vivo prediction of hepatobiliary disposition, hepatic uptake, hepatic efflux, biliary clearance and drug transport.

“The combination of CellzDirect’s hepatocyte expertise and technology and Qualyst’s patented technology will create robust hepatocyte testing systems to help pharmaceutical companies avoid costly drug development challenges and expedite the development of safe and effective drugs,” said Rob Brainin Vice President and General Manager of CellzDirect.

“Commercialization of the B-CLEAR® technology through CellzDirect will provide researchers with convenient access to this powerful approach, enabling them generate valuable data related to the disposition of their drugs.”

“We have long worked with CellzDirect and are excited to expand our relationship and accelerate the adoption of B CLEAR® across the drug discovery and development industry,” said Marc Sedam, Chief Operating Officer of Qualyst. “Drug transporter-based research is expanding dramatically and we believe working with CellzDirect will provide industry leadership in this area.”

The new hepatocyte testing system will be available as a service through Invitrogen in mid-December. The system will be available for purchase in early 2009. All B-CLEAR® products and services continue to be available from Qualyst.

CARLSBAD, CA—(BUSINESS WIRE)—January 10, 2008 — Invitrogen Announces Acquisition of CellzDirect

CellzDirect, a Market Leader in Hepatocyte-Based Primary Cell Products and Services

CARLSBAD, Calif.--(BUSINESS WIRE)--Jan. 10, 2008--Invitrogen Corporation (NASDAQ:IVGN), a provider of essential life science technologies for research, production and diagnostics, today announced it has entered into a definitive agreement to purchase privately-held CellzDirect, Inc., based in Research Triangle Park, North Carolina, in a cash transaction for approximately $57 million.

CellzDirect provides hepatocyte-based cell products and related services used in the testing of new drugs. Primary human hepatocytes are the most accepted model for predicting a compound's effects on enzymatic metabolism in the liver. Such testing, recommended by the Food and Drug Administration (FDA), can prevent costly failures in clinical trials. For this reason, CellzDirect's products are mainly used by pharmaceutical and biotech companies in research and development. Primary hepatocytes are also used in biomedical research to study liver diseases and to understand downstream implications of cellular function.

"CellzDirect's high-value products and services will greatly complement Invitrogen's market-leading portfolio of complete cell systems, including primary cells, media, matrices and growth factors," said Greg Lucier, Invitrogen's Chairman and Chief Executive Officer. "The purchase of CellzDirect follows our strategy of investing in high growth areas of the market, specifically specialty cell systems."

"CellzDirect has distinguished itself from other primary cell providers through scientific leadership, consultation with scientific and industry leaders, and constant communication with the medical community and regulatory bodies," added Nicolas Barthelemy, Invitrogen's Senior Vice President, Cell Systems.

CellzDirect was founded in 2001 and employs approximately 90 people at its sites in North Carolina and Austin, Texas. Twelve month revenue for calendar year 2007 is expected to be approximately $18 million.

"Combining with Invitrogen will enhance our already strong position in the primary cell market," said Scott Edelman, CellzDirect's Chief Executive Officer. "We expect CellzDirect's growth rates to benefit from cross-promotion and combination with Invitrogen's technologies for cell culture, molecular biology, and fluorescent detection, and from Invitrogen's world-class sales, marketing, and distribution capabilities."

The transaction is subject to customary closing conditions and is expected to close in the first quarter. The acquisition is expected to be EPS neutral in fiscal year 2008, becoming accretive in fiscal year 2009.
