Aequorea victoria GFP BRINGING DRUG DISCOVERY TO L I F E A license to the complete range of red-shifted and folding mutations from Aurora Biosciences, BioImage and Amersham Biosciences now available from a single source Green fluorescent protein (GFP) has a number of applications in drug discovery research. In particular, GFP can be used as a reporter molecule to build up a detailed picture of the distribution, trafficking and function of proteins within cells and to evaluate how drug candidates affect these processes in a cellular environment. GFP can be used in conjunction with almost any fluorescence microscope, fluorescence plate reader or fluorescence imager. However, it is most powerful when used in conjunction with live cells at sub-cellular resolution at high throughput.Therefore, the IN Cell Analysis System will exploit GFP technology to its full potential. Amersham Biosciences took out an exclusive license with the right to sub-license the GFP portfolio from BioImage, Denmark in November 2000. In August 2001, Amersham Biosciences signed a licensing agreement with Aurora Biosciences. Amersham Biosciences has immediate and exclusive sub-licensing rights in Europe and Japan and exclusive sub-licensing rights in the USA from October 1st for the use of GFP in the discovery and development of human therapeutics. GFP LICENSES Aequorea victoria GFP is the most characterized and best understood fluorescent protein. Wild type GFP derives from jellyfish existing in cold sea water. The introduction of certain folding mutations dramatically improves the yield of correctly folded GFP molecules at 37°C. Red-shifted mutations are also required to enable the fluorescence to be detected by standard laboratory fluorescence detection instruments. Both Aurora Biosciences and BioImage have granted patents in Europe and USA which claim these mutations. Amersham Biosciences has now pooled patent portfolios with Aurora Biosciences and BioImage to combine the intellectual property on folding and red-shifted mutations, simplifying the licensing position and creating a single license that covers all. The patent portfolio gives access to the commonly used GFPs such as EGFP as well as the blue, cyan and yellow color-shifted variants. The patent portfolio includes the following granted/issued patents: US 5,625,048 US 5,777,079 US 5,804,387 US 5,968,738 US 5,994,077 US 6,054,321 US 6,066,476 US 6,077,707 US 6,090,919 US 6,124,128 US 6,172,188 EP 851874 EP0804457 A number of additional patent applications from Aurora Biosciences, BioImage and Amersham Biosciences will also be included in the license. Aurora has exclusive rights to sublicense patented mutant GFP technology from BioImage and Amersham Biosciences to certain of their current licensees. Aurora also retain the right to sublicense these technologies in conjunction with the sale of their systems and instrumentation, and with their other fluorescent reporter technologies.
