Applied Biosystems Adjourns Special Meeting of Stockholders Until October 28, 2008; Votes, Proxies and Merger Consideration Elections Already Submitted Will Remain Valid

Consistent with its press release issued last week, Applied Biosystems Inc. (NYSE:ABI) adjourned Thursday's special meeting of stockholders relating to the pending merger with Invitrogen Corporation until 9:00 a.m. Eastern time on Tuesday, October 28, 2008 at 301 Merritt 7, Norwalk, CT 06851. The company clarified that previously granted proxies and votes for the special meeting and merger consideration elections previously submitted by stockholders remain valid. Applied Biosystems also stated that the deadline for submitting cash, stock, and mixed merger consideration elections is two business days prior to the closing of the merger, which is expected to occur in November 2008.

As previously announced, the special meeting was adjourned to give stockholders time to consider an amendment to the merger agreement between Applied Biosystems and Invitrogen and to review a joint proxy statement/prospectus supplement that Applied Biosystems and Invitrogen have mailed to their stockholders. Stockholders are encouraged to review the supplement and the related annex, as well as the joint proxy statement/prospectus and the related annexes that were previously distributed.

Stockholders of record of Applied Biosystems as of the close of business on September 5, 2008 are permitted to vote at the adjourned meeting – either by submitting a proxy card distributed with the joint proxy statement/prospectus or the supplement, by attending the meeting and voting in person or by following the instructions in the joint proxy statement/prospectus for telephone or internet voting. Any proxies that have already been submitted by stockholders in connection with the special meeting remain valid, as do any votes submitted by telephone or internet. Stockholders who have already submitted a proxy or voted need not take any action at this time unless they wish to change their votes. Stockholders who have not yet voted may do so until the special meeting, and all proxies and votes will remain revocable until the meeting has been concluded.

Under the terms of the merger agreement, Applied Biosystems stockholders have the right to elect to receive their merger consideration in the form of cash, Invitrogen stock, or a combination of cash and stock, subject to proration. Any elections to receive cash, stock, or mixed consideration that have already been submitted remain valid and are unaffected by the adjournment of the special meeting. Stockholders who have already made an election need not take any action at this time unless they wish to change their elections. Stockholders who either have not made an election or wish to change their election are encouraged to do so as soon as possible, and in any event by early November, to ensure that their elections are received and processed prior to the election deadline. The deadline for making an election is two business days prior to the closing of the merger, which is currently expected to be in November 2008. As previously disclosed, the exact deadline will be announced via press release at least five business days prior to the closing. Stockholders also should be attentive to any earlier deadlines imposed by their brokers.

Elections can be submitted by following the procedures outlined in the joint proxy statement/prospectus and the election form previously sent to stockholders. Properly completed election forms should be submitted to American Stock Transfer & Trust Co., as the exchange agent for the merger, at one of the following addresses:

Stockholders with questions regarding the election form should contact The Altman Group, the information agent for the merger, at (800) 332-4904.

Stockholders holding shares through a brokerage account or similar arrangement will need to follow any procedures required by their brokers, and stockholders are encouraged to consult with their brokers as soon as possible regarding these procedures. All election forms must be accompanied by a tender of the stockholder's shares, either by delivery of certificates or book-entry transfer. If you hold your shares through a brokerage account or similar arrangement, your broker will tender the shares on your behalf if you follow the broker's instructions.

Stockholders who do not submit an election form will receive the mixed consideration for each share of Applied Biosystems stock they own, which consists of $17.10 in cash, up to $1.05 of additional cash depending on the trading prices of Invitrogen common stock as the closing approaches, and 0.4543 of a share of Invitrogen common stock. Stockholders who do not submit an election form will receive a letter of transmittal and instructions to receive their merger consideration after completion of the merger.
