    Patent number: 6187269
    Abstract: Storage stability of an assay device, comprising an assay strip and sensitive reagents such as antibodies within a plastics casing, is maintained by moulding some or all of the casing from dessicant-containing plastics material, especially a blend of about 60-65% polystyrene and about 30% silica dust. Ideally the desiccant-containing plastics material is used in the moulding of a removable cap for the device. The cap can be made by sandwich injection moulding, using the dessicant-containing polystyrene as a core, surrounded by conventional polystyrene.
