  • Publication number: 20160022845
    Abstract: The present invention relates to an improved [18F]labelled synthon composition, wherein the non-radioactive impurities in said composition have been found to be more straightforward to remove than with known compositions comprising said [18F]labelled synthon. The resultant purified [18F]label led synthon therefore can be used in the production of a positron emission tomography (PET) tracer having improved properties for in vivo imaging. The invention also includes methods of imaging and/or diagnosis using the radiopharmaceutical compositions described.

  • Patent number: 9125954
    Abstract: The present invention provides a method for the synthesis of 18F-labelled biomolecules, which is amenable to automation. The present invention also provides a cassette for automating the method of the invention. The method of the present invention provides numerous advantages over the prior art methods. One less purification step is required as compared with known methods. Also, one less reagent is required as a particular reagent is employed in two different steps. The chemistry process is thereby simplified, the cost of goods is reduced and the burden of validation and documentation of reagents required for GMP clinical production is minimized.
