We screened the cdna expression library by using 12 b - deoxoartemisinyl - ( 4 ' - oxyacetic acid ) phenyl ether conjugated with bsa . one of the screened positive clones was inserted tctp of plasmodium falciparum from hainan . the tctp was cloned to express protein in order to provide materials for further study 把青篙素类衍生物: 12b一二氢青篙素( 4 ’一氧乙酸基)苯醚用bsa标记作为探针，对恶性疟原虫海南株cdna表达文库筛选，分离出插入了恶性疟原虫海南株tctp基因的阳性单克隆。
