摘要：
Varicella-zoster virus (VZV) is a highly infectious DNA virus that can cause varicella (chickenpox) and herpes zoster (HZ). A simple, sensitive and specific detection method is desirable for the VZV infection. In this study, VZV gE protein, expressed in CHO cells, was used to immunize BALB/c mice for the generation of monoclonal antibodies (mAbs). For the first time, we developed a colloidal gold-based immunochromatographic strip for rapid detection of VZV using a pair of mAbs against gE protein. The limit of detection (LOD) of the strip was 30 ng mL-1 of purified VZV gE antigen, and it could specifically test VZV without cross-reactivity with Enterovirus 71 (EV-71), Herpes simplex virus 1 (HSV-1) and Herpes simplex virus 2 (HSV-2). The coincidence rate between the strip and commercial real-time PCR diagnostic kit was 100% using vesicle as the clinical sample. Our strip provided a technical support for rapid and specific detection of VZV.
