LUNDBECK A/S SUBSCRIBES TO GPCR LOCALIZATION DATABASE

SEATTLE, WA (July 31, 2003) - LifeSpan Biosciences Inc announced today that Lundbeck A/S has subscribed to LifeSpan Biosciences' GPCR Localization Database.

The database, which is currently under development by LifeSpan, will eventually provide expression and localization information on 320 individual GPCRs. Under the contract, Lundbeck researchers will be able to view all GPCR-related information from a single, integrated bioinformatics platform and to engage in proprietary GPCR expression studies with LifeSpan. Financial terms of the agreement were not disclosed.

GPCRs are a family of cell-surface molecules that act as receptors for biologically active compounds. Nearly 50 percent of currently marketed pharmaceuticals are included in this group of biologically active compounds. LifeSpan is using its extensive bank of human tissue specimens and generating specific antibodies to GPCRs for use in immunohistochemistry to determine the expression and localization of individual GPCRs at the cellular level in a wide range of normal and diseased tissues. LifeSpan's molecular pathology approach requires highly trained pathologists to interpret staining patterns that reflect the distribution of gene products expressed in various tissues. As a result, this approach provides a degree of detail that cannot be achieved by high-throughput methods such as gene chips.

LifeSpan has compiled its detailed GPCR expression and localization information in an easy-to-search relational database that includes more than 250,000 high-resolution digital images, integrated with approximately 50,000 public DNA and protein sequences and 135,000 publications. Because of its unique emphasis on gene expression and localization in normal and diseased human tissues and cell types, LifeSpan's database is of particular value in helping subscribers pinpoint the most productive areas for drug research, identify and validate new targets for drug development, and flag potential side effects early in the drug development process.
