  • Assay using an unblocked solid phase with immobilized analyte binding partner
    Patent number: 5807752
    Abstract: The invention relates to a test system useful in carrying out diagnostic assays. One component of the test system is an unblocked solid phase test carrier with a three dimensional configuration, impregnated with a first binding partner for analyte of interest. The second component of a binding agent containing a second binding partner coupled to an immediately visually determinable label, and a blocking agent. Rapid and accurate assays may be carried out by using the described system.
