METHOD OF ASSAYING PHYSIOLOGICALLY ACTIVE SUBSTANCE OF BIOLOGICAL ORIGIN, KIT FOR ASSAYING PHYSIOLOGICALLY ACTIVE SUBSTANCE OF BIOLOGICAL ORIGIN AND APPARATUS FOR ASSAYING PHYSIOLOGICALLY ACTIVE SUBSTANCE OF BIOLOGICAL ORIGIN

摘要

Provided is a technique whereby a physiologically active substance of biological origin such as an endotoxin or &bgr;-D-glucan can be more conveniently and accurately detected and the concentration thereof can be determined even in the case of using a sample which contains a substance affecting LAL activity. For example, a sample is brought into contact with a substance (2) capable of adsorbing an endotoxin and thus the endotoxin contained in the sample is preliminarily adsorbed. Next, the sample per se is washed away and the adsorbed endotoxin (4) is reacted with LAL. Then the gelation of LAL or the formation of gel particles (5) is detected to thereby detecting the endotoxin and determining the concentration thereof.
