Abstract
A method for detecting the presence of a specific analyte in solution comprising the steps of affixing to a chromatographic medium a first antibody which binds with specificity to the analyte in a pattern which forms a pre-determined geometric symbol or symbols consisting of a plurality of line segments; partially blocking or obstructing the expected passage of a moving phase or solvent through the symbol; reacting the solution to a marker-second antibody complex which binds with specificity to the analyte to form analyte-marker-second antibody complexes in the presence of the analyte; eluting the solution containing any analyte-marker-second antibody complex through the partially blocked or obstructed medium; and observing the substantially complete formation, or lack thereof, of the predetermined geometric symbol or symbols by means of the marker.
