Do I need a licence for using GFP?
Not for companies testing on their own behalf. Gentronix has negotiated a license with Amersham Biosciences (now GE Healthcare) to use the GFP gene in our assay, which allows us to distribute our products worldwide. Individual users do not need a license to use GreenScreen products. However, Contract Research Organisations should contact Gentronix to discuss the requirements for using GreenScreen to provide a toxicology testing service to third parties.
