摘    要:将细菌内毒素检查法(凝胶法)扩大应用于乙脑灭活疫苗的质量控制及其内毒素的检测.按<中国药典>及<中国生物制品规程方法>方法,复核鲎试剂灵敏度、确定疫苗的L值、计算MVD、进行干扰试验及内毒素的检测.疫苗L值确定为300 EU/mL,MVD为1 200倍.用灵敏度0.25 EU/mL的鲎试剂,疫苗的最大非干扰浓度为将其稀释30倍,将此疫苗稀释120倍进行干扰试验,对内毒素的检测无干扰作用.以此法对15批疫苗进行内毒素检查均呈阴性反应.结果显示,此法用于乙脑灭活疫苗质量控制及其内毒素检查是可行的.

关 键 词:细菌内毒素检查法  鲎试剂  乙脑灭活疫苗

Abstract:Bacterial endotoxin test (GEL CLOT method) was employed expansively to control the quality and to detect endotoxin of Japanese Encephalitis Inactivated vaccine. The sensitivity of Tachypleus Amegocyte Lysate (TAL) was rechecked, the L value of vaccine was determined, the MVD was calculated to carry out the interfering test and endotoxin detection according to the requirements defined in Chinese Pharmacpoeis and Chinese Biological Products. The results showed that the L value was determined at 300 EU/mL; MVD was 1 200 times. When using TAL at 0.25 EU/mL of sensitivity, the dilution of maximum non interfering concentration was 30 times. When the vaccine was diluted 120 times to carry out interfering test, no interfering action of endotoxin was detected. This method appeared negative to 15 batches of vaccine in endotoxin detection. Therefore, this method is feasible for endotoxin detection of Japanese Encephalitis inactivated vaccine.
Keywords:Bacterial endotoxin test  Tachypleus Amebocyte Lysate (TAL)  Japanese encephalitis inactivated vaccine
