简介：HIV-1p24察觉提供一个工具帮助HIV-1感染的早诊断，追踪疾病的前进并且估计antiretroviral治疗的功效。在对HIV-1的现在的学习，三monoclonal抗体(mAbs)p3JB9，p5F1和p6F4，p24被产生。所有mAbs能检测HIV-1B，HIV-1Ada-M，HIV-174vmAbsp5F1和p6F4的p24能检测HIV-1KM018，当p3JB9不能时。三mAbs没与HIV-2ROD，HIV-2CBL-20和SIVagmTyo-1反应。p5F1的公认的epitope位于Gag氨基酸区域DCKTILKALGPAATLEEMMTAC。p5F1被用来与兔子anti-p24浆液建立修改三明治ELISA并且显示出好特性和高敏感，它被用来在研究测量HIV-1p24抗原层次。
