FOR IMMEDIATE RELEASE

INVITROGEN ANNOUNCES LEADER AND FORMATION OF INTEGRATION TEAM

Integration Team Will Drive Realization of $175 Million in

Expected Operating Profit Synergies by 2011, $60 Million in 2009

CARLSBAD, CA – June 20, 2008 – Invitrogen Corporation (NASDAQ: IVGN) today announced that Mark Smedley, Invitrogen’s Global Head of Operations, has been appointed to lead the integration team for the combination of Invitrogen and Applera’s Applied Biosystems Group (NYSE: ABI).

Mr. Smedley brings twenty years of experience in life sciences and pharmaceuticals to this new role, which spans global and senior leadership positions in operations, research and development, sales, marketing and program management, among others. Prior to joining Invitrogen, Mr. Smedley was with Novartis, where he participated in and led several global multi-business, multi-billion dollar integrations.

“The leadership teams of both companies have carefully considered the challenges and opportunities associated with bringing these two great companies together, and have launched a highly structured program to drive a seamless and efficient integration,” said Gregory T. Lucier, Chairman and Chief Executive Officer of Invitrogen. “We are fortunate to have an individual of Mark’s caliber leading the integration of this transaction. His discipline in operational process excellence and business leadership has enabled Invitrogen to significantly improve gross margin, operating margin and the overall customer experience.

“Mark has assembled a core leadership team of over 30 highly talented, dedicated and hand-picked ‘change agents’ from both organizations who will take the best parts of their own organizations to plan for a stronger, better combination,” Mr. Lucier added. “He has also retained a world-class integration advisor to work with him to drive the value we believe exists in this combination. Given Mark’s skill and proven ability to drive successful integrations, we are confident he will accomplish this significant effort.

“I am very excited about combining our two companies and the kick-off of the integration planning is the first step in achieving the full value of this transaction,” Mr. Lucier said. “After Applera instituted a process, and we completed significant due diligence, we believed that this combination would allow us to truly accelerate research and discovery and in turn create long term shareholder value. We envision the new company being structured into businesses of molecular and cellular


biology reagents, genetic sequencing systems and mass spectrometry. We believe this structure will enable us to continue to deliver superior innovation and a high level of customer service and support for all product lines, to ensure the success of our customers.”

Mr. Smedley said, “We have a solid and stable infrastructure from people to processes to systems. We have a leadership team that has demonstrated we can deliver upon a significant improvement to company performance in a very short time period.”

Invitrogen’s due diligence on the Applied Biosystems businesses confirmed that there are many opportunities for both cost synergies in the short term and future opportunities for accelerated revenue growth. The synergies identified are expected to be derived from $125 million in cost savings and $50 million in operating income from revenue synergies. Invitrogen believes that the cost synergies will be achieved through short term actions such as reducing redundant corporate overhead, raw material costs and licensing fees, as well as longer term projects such as creating manufacturing centers of excellence. Invitrogen expects that revenue synergies will be recognized through sharing Invitrogen’s best practices in mix optimization and e-commerce merchandising, as well as broadening the reach for both companies’ products into fast growing segments such as applied markets and emerging geographies.

The company reiterated that the transaction is expected to be neutral to slightly accretive in the first year after close of the transaction, inclusive of $60 million in realized synergies. Also included is an estimated $20 to $25 million of costs in order to achieve these synergies. In the first year following the close of the transaction, the combined company is expected to achieve mid-single digit organic revenue growth. In the second year after close of the transaction, the combination is expected to be significantly accretive and deliver earnings per share growth in excess of 20%. As is the case with Invitrogen, the combined company will continue to have a focus on accelerating organic growth, operating margin improvement and increasing ROIC.

The company also indicated that it believes it is on track to deliver yet another quarter of strong organic growth and double digit EPS growth.

As previously announced on June 12, 2008, the Boards of Directors of Invitrogen and Applera Corporation approved a definitive merger agreement under which Invitrogen will acquire all of the outstanding stock of Applera’s Applied Biosystems Group for $38.00 per share in a cash and stock transaction valued at $6.7 billion, based on an Invitrogen 20 day volume-weighted average price of $43.69—$46.00 three days prior to close. This consideration represents a premium of 17% to Applied Biosystems’ stock price on June 11, 2008. The transaction is targeted to close in the fall of 2008.
