Abstract:
A dry type multilayer analysis element for assaying a concentration of a specific component utilizing a competitive immunological reaction comprises a detection element comprising a detection layer which receives a labelled complex formed as a result of the competitive immunological reaction or an optically detectable change formed dependent upon an amount of the labelled complex of the specific component and having further provided thereon the detection layer a reaction layer comprising a fibrous porous medium containing fine particles therein. The multilayer analysis element absorbs an amount of a sample solution necessary for the competitive immunological reaction so that the multilayer analysis element has high sensitivity and high reproducibility.
Abstract:
A method for the simultaneous immunochemical assay of trace components in a sample involving competitively reacting the antigens or antibodies in a sample and labeled antigens or labeled antibodies for limited binding sites. The labels are spectral sensitizing dyes. The reaction products are contacted with silver halide and exposed to light having wavelengths corresponding to the absorption spectra of the spectral sensitizing dyes.
Abstract:
In a glove manufacturing device, a glove insert with thermoplastic adhesive applied on the outer side is fixed on a glove holding member in a state where it has been inserted into the inner side of the outer material of the glove. The glove insert is then expanded by way of a gas injection means, and the outer material of the glove and the glove insert are bonded. The glove holding member is fixed on the turntable and sent to a heating furnace by this rotating.
