Verfahren zur Bestimmung von Endotoxin |
摘要 |
The presence of endotoxin in the outer membrane of cell wall of a Gram-negative bacteria is used to determine bacterial contamination in a biological product. The amount of endotoxin present in a biological product is accurately measured without infuluence of a limulus reaction-activating substance which causes a false-positive reaction, by a method including the steps of: inactivating the limulus reaction-activating substance, if any, in the biological product, by exposing the biological product to a surfactant at a temperature ranging from the surfactant's freezing point to 50 DEG C; and measuring the amount of endotoxin present in the biological product, using a limulus reagent. |
