Abstract
An agglutination assay reagent and method. The reagent is composed of liposomes predominantly in the 1 to 20 micron diameter size range. Each liposome has a surface array of laterally mobile ligand molecules, at a surface concentration adapted to produce reagent agglutination within about 5 minutes, when the reagent is incubated at room temperature with a multivalent ligand-binding analyte. A dye in the liposomes allows such agglutination to be visualized easily without magnification.
