  • Assay for an analyte on a solid porous support
    Patent number: 5202432
    Abstract: An assay for an analyte wherein sample is applied to a support capable of binding proteins by essentially only hydrogen bonding and fixed on the support. Analyte may be determined on the support by use of a suitable tracer. A preferred support is amphiphilic cellulose acetate. In an immunoassay, it is possible to determine analyte without use of a supported ("capture") antibody.
