目的:验证运用有机溶剂/去污剂(S/D)处理法和干热法对C1酯酶抑制剂(C1-INH)中病毒灭活效果。方法:采用S/D处理法灭活含S/D样品中添加的辛德毕斯病毒,噬斑滴定法检测灭活前后的病毒滴度,-干热法灭活脑心肌炎病毒(EMCV)和猪细小病毒(PPV)...目的:验证运用有机溶剂/去污剂(S/D)处理法和干热法对C1酯酶抑制剂(C1-INH)中病毒灭活效果。方法:采用S/D处理法灭活含S/D样品中添加的辛德毕斯病毒,噬斑滴定法检测灭活前后的病毒滴度,-干热法灭活脑心肌炎病毒(EMCV)和猪细小病毒(PPV),细胞病变法检测灭活前后的病毒滴度。结果:经S/D处理法灭活后,3批含S/D样品中辛德毕斯病毒降低量分别为>4.35 lg PFU·mL^(-1)、>4.51 lg PFU·mL^(-1)、>4.64 lg PFU·mL^(-1)。经干热法灭活后,3批不含S/D样品中EMCV降低量分别为≥5.38 lg TCID_(50)/0.1 mL、≥5.12 lg TCID_(50)/0.1 mL、≥5.25 lg TCID_(50)/0.1 mL,PPV降低量分别为4.57 lg TCID_(50)/0.1 mL、4.18 lg TCID_(50)/0.1 mL、4.68 lg TCID_(50)/0.1 mL。结论:通过对指示病毒的验证效果评估,证明S/D法和干热法对C1-INH中的辛德毕斯病毒、EMCV和PPV均有较好的灭活效果。展开更多
