Materials and Methods: CT scan cheeked epidural hematoma and subdural hematoma in11 cases. 材料与方法:CT扫描证实硬膜外、硬膜下血肿11例。
After induced by IPTG and cultured for some lime, the pDH/ BL21 bacterial strain was cheeked by SDS-PAGE ( SDS polyacrylamide gel electrophoresis). We found that the recombinant vector expressed a new protein of which the molecular weight was about 21 kDa. 筛选得到的pDH/BL21菌株利用IPTG诱导培养后,经SDS聚丙烯酰胺凝胶电泳(SDS-PAGE)检测发现,该菌株表达有一大小约21kDa的外源蛋白。
