    摘要: In a composition which has an amorphous, undercooled, glassy phase containing a water-soluble or water-swellable substance in an amorphous form, a sugar, which is capable of existing as a crystalline hydrate, is used as an agent to dehydrate the amorphous phase by crystallization therefrom, and thereby enhance the glass transition temperature of the residual amorphous phase.

    摘要: In a composition which has an amorphous, undercooled, glassy phase containing a water-soluble or water-swellable substance in an amorphous form, a sugar, which is capable of existing as a crystalline hydrate, is used as an agent to dehydrate the amorphous phase by crystallisation therefrom, and thereby enhance the glass transition temperature of the residual amorphous phase.

    摘要: A material or mixture of materials which is not itself storage stable is rendered storage stable by incorporation into a water-soluble or swellable glassy or rubbery composition which can then be stored at ambient temperature. Recovery is by adding aqueous solution to the composition.

    摘要: 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.

    摘要: The use of raffinose as a glass-forming agent for freeze-dried compositions intended for use in conducting chemical or biochemical reactions such as the PCR. Thus, for instance, there is provided a composition for carrying out a chemical or biochemical reaction, said composition being in a freeze-dried form and comprising (i) a set of reagents comprising at least some of the chemical or biochemical reagents necessary for conducting said chemical or biochemical reaction, and (ii) raffinose. Kits comprising these compositions and methods of using them form a further aspect of the invention.

    摘要: Material which contains water, or is accompanied by an aqueous phase, notably biological cells, cell components or cell aggregates, or differentiated biological tissue is preserved by dispersion in an oil medium and under-cooling the dispersion, preferably to a temperature in the range -20.degree. C. to -40.degree. C. The oil medium is characterized by the absence of surfactant which can catalyze ice formation and is an immobile gel at the storage temperature. The preferred oil 10 medium is paraffin oil, or oil plus paraffin wax.
