  • Storage of materials
    Patent number: 6825031
    Abstract: Materials which are not themselves storage-stable at room temperature are made suitable for storage by mixing them with a carrier substance and spray drying the resulting mixture so as to form particles containing both the material and the carrier substance in which the carrier substance is in an amorphous, i.e. glassy or rubbery, state. Formation of such a composition greatly enhances stability. The material stored may be a biological material such as an enzyme, the components of a chemical reaction such as reagents for carrying out an assay, or even viable biological cells.
    Type: Grant
    Filed: February 8, 2002
    Date of Patent: November 30, 2004
    Assignee: Nektar Therapeutics
    Inventors: Felix Franks, Ross Henry Hatley, Sheila Frances Mathias
