    摘要： Disclosed 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.

    摘要： Disclosed is a boron adsorbent having an excellent adsorbing ability against boron contained in a solution, which is inexpensive and has high general versatility. Also disclosed is a boron removal method which can remove boron efficiently in a simple manner. An amide derivative represented by the general formula (1) is added to a boron-containing water under alkaline conditions to cause the adsorption of boron to the amide derivative. Then, a cation source having two or more valencies is added to the water to cause the aggregation of the amide body. The aggregated amide body is removed from the water. In the general formula (1), m represents 1 or 2; X represents —CH2OH, —CHO or —COOH; n represents an integer of 2 to 5; X are independent from each other and n are independent from each other when m represents 2; and Y represents a monovalent hydrocarbon group having 6 to 16 carbon atoms when m is 1, and represents a divalent hydrocarbon group having 8 to 18 carbon atoms when m is 2.

    摘要： A technique which is less likely to be affected by turbid or color of samples and with which prompt and simple detection or concentration measurement of endotoxin can be achieved is provided. A reagent in which proteins contained in LAL are adsorbed or bound onto fine particles dispersed in a previously prepared drug liquid is prepared, and this reagent and a sample containing endotoxin are mixed. By doing this, endotoxin acts on the proteins on the fine particles and the fine particles are associated with one another to form a large aggregate at an early stage. By optically measuring the formation of this aggregate, detection or concentration measurement of endotoxin is performed.
