四川大学学报. 自然科学版, 2006 将编码麻疯树逆境蛋白curcin 2成熟蛋白的M片段和编码前体蛋白的P片段分别定向克隆到质粒载体pQE-30、pQE-31后,获得重组质粒pQE-30-M、pQE-31-P.该重组质粒转化大肠杆菌M15菌株,经IPTG诱导后M片段表达的蛋白质主要以包涵体形式存在,蛋白质的表达量与IPTG浓度及诱导时间有关.重组蛋白可与RGS-His抗体及curcin抗体分别发生专一性抗原抗体反应并被His TrapTMHP柱亲和纯化.体外抗真菌活性实验表明,复性处理后的curcin 2融合蛋白使玉米弯胞杆菌 ...

Jianzhu Gangjiegou Jinzhan对钢框架-灌浆轻钢剪力墙结构足尺试件进行了水平低周往复加载试验，研究了灌浆轻钢剪力墙与钢框架的耦合效应，分析了结构的破坏模式、受力特征和耗能机理，得到了结构的承载能力、抗侧刚度、延性及耗能能力等。通过与纯钢框架及冷弯薄壁型钢灌浆墙体结构的试验结果对比，发现灌浆轻钢剪力墙通过自攻螺钉采用内嵌的方式与钢框架连接，二者具有良好的协同工作性能，框剪结构的抗剪承载力和抗侧刚度分别是钢框与墙体对应值之和的1.50倍和1.64倍，结构延性系数达5.42，抗震性能优良，研究结果可为该类结构的设计研究提供科学基础。
