Abstract
Abstract THE IMMUNOLOGICAL INDICATOR DISCLOSED IS MADE BY ATTACHING CHEMICAL COUPLING AGENTS TO MICROBIAL CELLS WHICH SERVE AS INDICATOR PARTICLES. ANY ANTIGENIC MATERIAL CAN THEN BE CHEMICALLY ATTCHED THERETO IN ORDER TO FORM A SPECIFIC INDICATOR SYSTEM FOR THAT ANTIGENIC MATERIAL. A WIDE RANGE OF MICROBIAL CELLS AND COUPLING AGENTS MAY BE USED TO FORM INDICATOR SYSTEMS WHICH ALLOW IMMUNOLOGICAL TESTS TO BE CONDUCTED THROUGH THE MECHANSIMS OF AGGLUTINATION OR INHIBITION OF AGGLUTINATION, AND THROUGH A CHROMATOGRAPHIC TECHNIQUE.
