下面来看具体的研究结果： NePabS 的生产与纯化：研究人员将编码欧洲亚硝化单胞菌（Nitrosomonas europaea）pABA 合酶的基因 ne1434 插入 pET15b 载体，在大肠杆菌 BL21 中进行表达和纯化。金属分析显示，纯化后的蛋白质中铁的含量较低，表明其金属辅因子不稳定 ...

Insulin-like growth factor-I receptor (IGF-IR) preferentially regulates the long-term IGF activities including growth and metabolism. Kinetics of ligand-dependent IGF-IR endocytosis determines how IGF ...

The resulting HA-fused cDNAs were PCR amplified using an Xho I-HA-upstream primer and downstream T3 primer. The PCR products were digested with Xho I and introduced into the Xho I site of pET15b ...
