  • Compilation of detection reagents, in-vitro method for detecting mutated leptin, and use of a detection reagent
    Patent number: 10175253
    Abstract: The invention relates to a compilation of detection reagents, wherein the compilation comprises a first and a second detection reagent, wherein the first detection reagent binds non-mutated leptin with a first binding value, but does not bind mutated leptin or binds it with a maximum of 50% of the binding value of non-mutated leptin, and wherein the second detection reagent binds both mutated and non-mutated leptin with a second binding value. The invention furthermore relates to an in-vitro method for detecting mutated leptin and the use of a detection reagent.

  • Hepatitis-A viruses adapted to human fibroblast cells
    Patent number: 4506016
    Abstract: Hepatitis-A virus, suitable for use in human or animal vaccines, is prepared by adapting the virus first to human kidney cells and subsequently adapting the thus-altered virus to human fibroblast strains. In the process the growth rate of Hepatitis-A virus on the noted tissues is materially increased. This HAV is also a useful antigen in diagnostic test procedures.
