    摘要: A completely water-soluble, solid, labile biochemical-containing diagnostic reagent is prepared without the need of a lyophilization step, by spraying, preferably by a fluidized bed process, an aqueous solution of labile biochemical, e.g., an enzyme, onto small particles, e.g., lower than 20 mesh, of an inert, completely water-soluble solid bulking agent, e.g., mannitol; drying the resultant labile biochemical-coated bulking agent to the desired dryness; and then forming resultant dried labile biochemical-coated bulking agent into a tablet suitable for a diagnostic test reagent, said tablet having a predetermined rate of dissolution.

    摘要: Systems and methods for using stamps to print or mask materials on a substrate service. In one particular embodiment, the systems and methods include a microcontacting stamp that has a plurality of rigid posts each having a resilient pad at its distal end. Each post is fitted within an aperture located in a guide plate such that the post may move longitudinally within the guide plate. The guide plate includes a variety of apertures that typically are aligned with the wells of a microtiter plate. The apertures extend typically through the entire thickness of the guide plate. On one side of the guide plate is a resilient member that extends over one or more of the apertures thereby holding the post in place.

    摘要: A quantitative test device is manufactured using a feedback loop which allows one to modify continuously the dimensions of a reading scale printed on the device. The quantitative test device is manufactured by attaching the critical component of a two-component dye system to minute particles such as microcrystalline cellulose, silica, or latex, which particles are suspended in a solution of a polymeric binder. Additional non-immobilized components of the reaction system of the test device are optionally added to the polymer solution. The suspension of dyed particles in polymer solution is applied to a fabric as a coating, using conventional coating machines, to obtain a homogeneous distribution of immobilized dye throughout the fabric.The device includes a measurement zone which is made from a film support made of a material having a lower melting point than the filter cloth fabric used in the measurement zone was used. By using a lower melting point material for the support film, impulse heat sealing is controlled to a degree such that the lower melting point support is made to melt and extrude through the mesh of the fabric on either side of a channel, forming a seal along the sides of the channel.

    摘要: Red blood cells are removed from whole blood or a fraction thereof by agglutinating whole blood with a mixture of a free agglutinating agent and nucleating particles having agglutinating agent intimately associated therewith to form clusters of red blood cells. High molecular weight polyethylene glycol may be added further to enhance agglutination. The clusters of red blood cells are much larger than the size of individual red blood cells, so that the clusters can easily be filtered through a porous medium. The plasma, which is substantially free of red blood cells, is further passed through a filter that optionally contains an additional agglutinating agent. Flow-delay additives may be provided to retain the fluid sample in contact with a reagent for a predetermined time.
