Results By optimization test, capture antibody and detection antibody (from PVA detection kit, Agdia, USA) were finally diluted at 1:50 (4ug/mL) and 1:25 to be used in one step CBA, respectively. A total CBA reaction time of 2 h was needed. No cross reactivity with other plant virus similar to potato virus Y, lettuce mosaic virus and tomato ring spot virus were found. Detection sensitivity for positive control sample in one-step CBA was 4 folds higher than that in normal plate double antibodies sandwich enzyme-linked immunosorbent assay.

通过实验优化检测条件，最佳捕获抗体工作浓度为4μg/mL、最佳检测抗体工作浓度为1：25倍稀释、最佳反应时间为2h；与马铃薯Y病毒、莴苣花叶病毒、番茄环斑病毒等均未出现交叉反应；阳性样品经64倍稀释后依然可检出，检测灵敏度是传统微孔板ELISA的4倍。
