A method of testing phenotypic drug susceptibility in an enveloped virus-infected mammalian individual by testing on an enzyme packed into an enveloped virus, such as HIV, recovered from a biological sample, such as blood or plasma, from said individual is described. The method comprises the steps of a) adding an enzyme inactivating agent to the sample for inactivating polymerase activity other than that present in the enveloped virion, b) removing the enzyme inactivating agent, enzyme activity blocking antibodies, endogenous enzyme activity inhibitors and antiviral drugs, c) lysing the virus particle to release the enzyme, d) recovering the concentrated purified viral enzyme, such as a HIV reverse transcriptase (RT), resulting from c) and determining the drug sensitivity profile of the individual from the recovered enzyme by using sensitive enzyme assays. The drug sensitivity profile may be used for selecting drug treatment therapy. A commercial package is included.
本发明描述了一种方法,该方法通过检测从生物样本(如血液或血浆)中回收的包膜病毒(如艾滋病毒)中的酶,来检测受包膜病毒感染的哺乳动物个体的表型药物敏感性。该方法包括以下步骤:a) 向样本中添加酶灭活剂,用于灭活包膜病毒中聚合酶活性以外的酶活性;b) 去除酶灭活剂、酶活性阻断抗体、内源性酶活性抑制剂和抗病毒药物、c) 裂解病毒颗粒以释放酶, d) 回收 c) 中浓缩纯化的病毒酶,如 HIV 逆转录酶 (RT),并使用敏感酶测定法从回收的酶中确定个体的药物敏感性概况。药物敏感性曲线可用于选择药物治疗疗法。包括一个商业软件包。
