Abstract

A simple and rapid immunochromatographic assay (ICA) to detect (SDV) was developed using colloidal gold conjugates of anti-SDV monoclonal antibodies. Of six homogenization buffers tested, 0.1 M citrate buffer (pH 7.0) gave the best results for the ICA. In the ICA, addition of 0.1% thioglycolic acid in the homogenization buffers that have been widely used in enzyme-linked immunosorbent assays (ELISA) was deleterious to the reaction because of undesirable coagulation of the colloidal gold. ICA using the anti-SDV monoclonal antibodies was 8 times and 16 times more sensitive than double antibody sandwich-ELISA and ICA using the anti-SDV polyclonal antibody, respectively. The analysis is complete in only 15 min. Furthermore, ICA using the anti-SDV monoclonal antibodies could also detect SDV-related viruses.

摘要

利用抗猪德尔塔冠状病毒(SDV)单克隆抗体的胶体金偶联物,开发了一种简单快速的免疫层析检测法(ICA)来检测SDV。在测试的六种匀浆缓冲液中,0.1 M柠檬酸盐缓冲液(pH 7.0)在ICA检测中效果最佳。在ICA检测中,在酶联免疫吸附测定(ELISA)中广泛使用的匀浆缓冲液中添加0.1%巯基乙酸对反应有害,因为会导致胶体金出现不良凝聚。使用抗SDV单克隆抗体的ICA分别比双抗体夹心ELISA和使用抗SDV多克隆抗体的ICA灵敏8倍和16倍。该分析仅需15分钟即可完成。此外,使用抗SDV单克隆抗体的ICA还可以检测与SDV相关的病毒。
