Abstract:
1. A liquid composition comprising a colloidal suspension of a biomolecule-binding matrix material uniformly dispersed in a liquid, wherein colloidal particles of said matrix material in said colloidal suspension are of a defined particle size of less than about 1 μm in diameter, and wherein said biomolecule-binding matrix material is selected from the group consisting of nitrocellulose, polyvinyl difluoride and activated nylon; replicate copies of a biologically active labeled biomolecule, wherein said biomolecules are distributed throughout said colloidal suspension and are bound to said matrix material particles and wherein said biomolecule is selected from the group consisting of a protein, peptide and oligopeptide; one or more reference dyes distributed throughout said colloidal suspension; and a blocking biomolecule, wherein said blocking biomolecule blocks sites on said biomolecule-binding matrix material not occupied by said biomolecule.
