INVITROGEN RECEIVES FDA CLEARANCE FOR DIAGNOSTIC SYSTEM TO HELP DETERMINE TRANSPLANT COMPATIBILITY

Invitrogen Corporation (NASDAQ:IVGN), a provider of essential life science technologies for research, production and diagnostics, today announced it received U.S. Food and Drug Administration (FDA) clearance for its DynaChip(TM) Antibody Analysis System. The DynaChip(TM) system is the only automated chip-based system for human leukocyte antigen (HLA) antibody detection and identification. This is the first Class II IVD (Instrument, Interpretation Software, Assay) Medical Device System for which

Invitrogen has received FDA 510k clearance.

"We're very pleased to have received this FDA approval, which validates the accuracy of DynaChip data and demonstrates Invitrogen's commitment to providing clinicians with accurate and more efficient solutions," said Kip Miller, Senior Vice President of BioDiscovery.

Human leukocyte antigens are proteins found on the surface of certain cells in the body that are used by the immune system to identify material foreign to the body, such as viruses or bacteria. HLA antibody identification is important for organ transplant donor-recipient matching. In the case of organ donation, a patient's immune system may fight cells from the donor, causing organ donation failure or rejection.

The DynaChip(TM) Antibody Analysis System provides fully integrated instrumentation, reagents and software for automated detection and identification of HLA antibodies. The DynaChip(TM) Antibody Analysis System is composed of three parts:

-- The DynaChip(TM) Processor automates assay processing - from dispensing, incubation and washing to image detection and results analysis;

-- The DynaChip(TM) protein array allows users to test for multiple antibodies at the same time;

-- The DynaChip(TM) interpretation software provides rapid, efficient and automated analysis.

"The high capacity of the DynaChip allows us to add a larger number of proteins than competitive products, reducing the amount of testing and overall turn-around time," added Jim Janicki, Vice President and General Manager of Invitrogen's Applied Markets business unit. "With organ donations, time is of the essence and this analysis system will help physicians make fast, reliable clinical decisions."
