Microarray technology is currently present in UVS as a partnership with IFOM in Milano. This gives us access to 25 000 human Unigene clones. This collection is physically present in UVS and is ordered. In the framework of this application, we plan to organise a Microarray Core Facility and Bioinformatics service (MCFB), that should provide a spotting service on the solid supports, hybridization to investigator-provided cDNA preparations, and reading and analysis of the hybridization signals. The technical details of the system that will be chosen have not been finalized, but we reckon that this service will be essential for the support of most research lines in UVS.
