The concentration of glycosaminoglycans, in an aqueous solution was determined by observing the fluorescent intensity of the ion of 2-hexadecyl-9H-pyrido[4,3b]indole at 450 nm by irradiating 253-nm light after dissolution of the insoluble salt in ethanol, which was formed by the reaction between a solution of a sample of glycosaminoglycan and an aqueous solution of the binary mixture of fluorescent 2-hexadecyl-9H-pyrido[4,3b]indolium bromide and hexadecyl pyridinium chloride. The fluorescent quaternary ammonium salt, which was slightly soluble in water, was solubilized in water by forming mixed micelles with a nonfluorescent soluble quaternary ammonium salt. The present method showed good linearity for the calibration curves between 5 and 1000 micrograms/ml in all samples of glycosaminoglycan except keratan sulfate. The relative standard deviation in determination was less than 3% for the whole calibration range.
