    摘要: In a photochemical immunological assay, an antigen or antibody is labelled with a spectral sensitizer or fogging agent for photographic use, and then an immune reaction is caused. The resulting reaction mixture is dropwise added to a multilayer analysis sheet. After either one of the labelled antigen or antibody (F) or the labelled antigen-antibody bound product (B) is brought into contact with silver halide by passing either one through a B/F separating layer provided in the multilayer analysis sheet, the analysis sheet is exposed with a light that the spectral sensitizer or fogging agent absorbs. Then, the resulting optical density obtained by development processing when a spectral sensitizer is used, or without development processing when a fogging agent is used is measured.The multilayer analysis sheet comprises a support having provided thereon a silver halide layer and a B/F separating layer and makes the photochemical immunological assay simpler and more accurate.

    摘要: Microcapsules are sensitized with antibody to antigen of lymphocyte. Using such microcapsules, B cells and/or T cells can be selectively measured separately or simultaneously, in a simple manner, based on cell-mediated immunity which comprises applying the microcapsules sensitized with antibody to antigen of lymphocyte and sheep red cells or another kind of antibody-sensitized microcapsules that are optically distinguishable from the first antibody-sensitized microcapsules, to lymphocyte at the same time and thereafter independently measuring respective cells that are optically distinguishable from each other.The operation for the measurement is extremely simple and neither skill nor special equipment is required.

    摘要: Method for immunological analysis of a trace component(s) by labelling an antigen or antibody with a marker comprising causing an immune reaction using an antigen or antibody labelled with a spectral sensitizer as a marker, separating the labelled antigen or antibody from the resulting antigen-antibody reaction product, then bringing either the labelled antigen or antibody and the labelled antigen-antibody reaction product into contact with a silver halide, exposing the resulting system to light having a wavelength which the spectral sensitizer absorbs, developing the thus exposed silver halide and then measuring the resulting density.Trace components can thus be photochemically detected and the amount present quantitatively determined. The method provides high reproducibility and high sensitivity comparable to radioimmunoassay but without any risk of radiation exposure.

    摘要: An immunoassay process for quantitative analysis of an analyte antigen (or analyte antibody) in an aqueous liquid sample. In the first step, the analyte antigen (or analyte antibody) is allowed to react with an antibody (or antigen) in competition with a known quantity of a labelled antigen (or labelled antibody), the antibody (or antigen) being carried by water-insoluble microparticles in the immobilized state. In the second step, the reaction mixture is spotted on a top porous layer of an integral multi-layered analysis element which includes the top porous layer, an intermediate detection layer and a bottom water-impermeable and transparent support. The top porous layer permeates aqueous solution and has pores sufficiently small to trap all of the microparticles carrying the antibodies (or antigens) bound to the analyte antigen (or analyte antibody) and bound to the labelled antigen (or labelled antibody). Thus, the free labelled antigen is allowed to pass through the top porous layer and migrate to the detection layer. In the third step, the quantity of the marker labelling to the labelled antigen (or labelled antibody) which has not been bound to the immobilized antibody (immobilized antigen) is determined.
