Abstract
Abstract A REACTION RATE BETWEEN AN ENZYME REACTANT AND A SUBSTRATE REACTANT IS FLUROMETRICALLY MEASURED BY FORMING A SOLID REACTANT FILM OF ONE OF THE REACTANTS ON A SILICONE MATRIX PAD. THE REACTANT FILM IS THEN CONTACTED WITH A SOLUTIONS OF THE OTHER REACTANT TO PRODUCE A FLUORESCENT MATERIAL. THE CHANGE OF FLUORESCENCE WITH TIME IS MEASURED BY PLACING THE PAD IN A FLUROMETER AND THIS RATE OF CHANGE IS COMPARED AGAINST A CALIBRATION CURVE TO DETERMINE THE CONCENTRATION OF THE REACTANT IN THE REACTANT SOLUTION.
