<p>Discolosed is a technique which simplifies the adjustment of a reagent which makes the proteins contained in limulus amoebocyte lysate (LAL) attach to the surface of microparticles dispersed in a prepared drug solution, and which can improve the accuracy of the detection of a predetermined physiologically active substance or the measurement of the concentration thereof. A reagent is prepared which adsorbs the proteins contained in LAL to beads dispersed in a drug solution prepared in advance. By reacting a sample containing an endotoxin with the reagent, groups of the beads associate and rapidly form large aggregates, and measurement of the endotoxin is carried out by the detecting the formation of the aggregates. The beads are formed from an inorganic material such as alumina, kaolin, or manganese oxide.</p> |
