method of measuring a physiologically active substance of biological origin and, particulates and extract used to it

摘要

Is or very low sample concentration of the physiologically active substance derived from an organism, even for a sample containing a component having an interference effect with respect to AL, more accurately, or, in less time, and detecting the physiologically active substance of biological origin or measurement of the concentration is to provide a possible technology. The sample containing the predetermined physiologically active substance such as endotoxin and dispersing the adsorbed microparticles of the predetermined physiologically active substance, to concentrate the predetermined physiologically active substance in the sample by adsorbing the predetermined physiologically active substance in the microparticles. Thereafter, microparticles were separated recovered to induce aggregation reaction by reacting with the AL, and performs measurement of the predetermined physiologically active substance by detecting the flocculation by optical means.
