    • The invention provides methods and compositions for the detection and/or quantification of bacterial endotoxins. In particular, provided herein is an inexpensive and reproducible method for producing an improved amebocyte lysate preparation having reduced Factor G activity. Provided also is an endotoxin-specific amebocyte lysate preparation produced by such a method. In addition, the invention provides methods and compositions for enhancing the sensitivity to endotoxins of amebocyte lysate preparations having reducing Factor G activity. In particular, the sensitivity of such amebocyte lysate preparations to endotoxins can be enhanced by the addition of exogenous (1}3) beta -D-glucan.
    • 本发明提供用于检测和/或定量细菌内毒素的方法和组合物。 特别地,本文提供了一种廉价且可重现的方法,用于生产具有降低的因子G活性的改良的血小板裂解物制剂。 还提供了通过这种方法制备的内毒素特异性的单核细胞裂解物制剂。 此外,本发明提供用于增强具有降低因子G活性的微血管细胞裂解物制剂对内毒素敏感性的方法和组合物。 特别地,通过加入外源(1)3)β-D-葡聚糖,可以增强这种细胞裂解物制剂对内毒素的敏感性。

    • A method of assaying a Limulus reagent-reactive substance (endotoxin or (1}3)- beta -D-glucan) in a specimen by the turbidimetric Limulus test without being affected by any interfering substance with high sensitivity and high accuracy, which method comprises treating a specimen solution with a Limulus reagent to cause gelation, irradiating the resulting solution with the rays of light having a measurement wavelength of 460-550 nm and the other rays of light having a reference wavelength of 650-800 nm to detect a change in the absorbance of the transmitted light on the basis of the rise of the solution turbidity caused by the gelation, and establishing a relationship between the concentration of the Limulus reagent-reactive substance and the difference in absorbance between the two rays of light.
    • 通过比浊鲎试验测定样品中的鲎试剂反应物质(内毒素或(1)3)-β-D-葡聚糖)的方法,不受高灵敏度和高精度的任何干扰物质的影响,该方法包括 用鲎试剂处理样品溶液引起凝胶化,用测量波长为460-550nm的光线照射所得到的溶液,并且使用参考波长为650-800nm的其他光线来检测变化 基于由凝胶化引起的溶液浊度的升高引起的透射光的吸光度,并且确定鲎试剂反应物质的浓度与两束光线之间的吸光度差之间的关系。

    • In a method of determining the presence of an endotoxin or endotoxin-like material in a sample, a) a sample is incubated with a component of horseshoe crab amoebocytes lysate or haemolymph or a synthetic analogue thereof, b) the incubated mixture of the sample and the component or analogue resulting from step a) is reacted with an antibody raised against the component or analogue or against a reaction product of the incubation of step a), and c) the presence of endotoxin or endotoxin-like material in the sample is determined by detecting any bound antibody in the reaction mixture of step b). In the method either the component or analogue or the antibody or the endotoxin or endotoxin-like material is coupled to a solid support.
