homoacetogenic bacteria

XRD results show that all ceramic samples are perovskite and the morphotropic phase boundary(MPB)is located in x=0.

5TiO3系压电陶瓷,XRD分析表明所得陶瓷样品为纯的钙钛矿结构,其准同型相界在x=0。

Objective To express and purify a single chain antibody (scFv)5C1 which specifically reacted to acute myelogenous leukemia cell line KG1a cell.

方法　基因重组构建表达 5C1scFv的载体pSTE 5C1,在大肠杆菌中诱导表达 ,金属离子螯和亲和层析法纯化 ,获得高纯度的活性 5C1scFv ;借助生物素 链亲和素的高亲和力和高灵敏度的显色系统 ,用Westernblot分析其识别的KG1a细胞膜蛋白的Mr;用聚集实验分析 5C1scFv对KG1a细胞同型聚集的影响。
