曼氏血吸虫活动性感染期释放于血液中的循环阳极抗原(CAA)是一种有诊断价值的标志物。应用传统的滤纸干血片检测CAA时,CAA被吸附于纤维滤纸上,难以被洗脱用于ELISA检测。作者应用一种聚丙烯合成纤维材料收集血样,能较好地洗脱出曼氏血吸虫的特异CAA和循环阴极抗原(CCA)。
Circulating anodic antigen (CAA) released into the blood during the active infection stage of Schistosoma mansoni is a diagnostic marker. CAA is adsorbed on the fiber filter paper when using traditional filter paper dry blood chip detection, it is difficult to be elution for ELISA testing. The authors used a polypropylene synthetic fiber material to collect blood samples that eluted the specific CAA and circulating cathodic antigen (CCA) of Schistosoma mansoni.
