Novagen′s Rosetta 2宿主菌株是BL21衍生物,旨在增强真核蛋白的表达,该蛋白含有在大肠杆菌中很少使用的密码子。
将DNA质粒转化为大肠杆菌的常用方法是使用化学感受态细胞。尽管可以在实验室中制备感受态细胞,但是使用Novagen制备的感受态细胞可以实现更高的效率、可重复性和便利性。Novagen感受态细胞代表了可用于蛋白质表达的最广泛选择。每个Novagen感受态细胞株均经过表型和纯度验证,并保证转化效率。T7表达菌株是噬菌体DE3的溶原菌,如(DE3)所示。这些宿主在lacUV5启动子的控制下携带T7 RNA聚合酶基因的染色体拷贝。这样的菌株适用于使用IPTG作为诱导剂,从在合适的T7表达载体中克隆的靶基因生产蛋白质。
Rosetta 2宿主菌株是BL21衍生物,旨在增强真核蛋白的表达,该真核蛋白含有在大肠杆菌中很少使用的密码子。这些菌株在兼容的氯霉素抗性质粒上为7种稀有密码子(AGA、AGG、AUA、CUA、GGA、CCC和CGG)提供tRNA。tRNA基因由其天然启动子驱动。
DE3表明宿主是λDE3的溶原菌,因此在lacUV5启动子的控制下携带T7 RNA聚合酶基因的染色体拷贝。这样的菌株适用于通过用IPTG诱导从克隆在pET载体中的靶基因生产蛋白质。

Diphenylphosphonates (DPPs) have been used for 50 years to inactivate serine hydrolases, creating adducts representative of tetrahedral intermediates of this important class of enzymes. Failure to react at active site serine residues, however, can thwart their usefulness. Here, we describe

The Cdk5 kinase plays prominent roles in nervous system development, plasticity, behavior and disease. It also has important, non-neuronal functions in cancer, the immune system and insulin secretion. At present, we do not fully understand negative regulatory mechanisms that restrict

The autophagy cargo receptor p62 facilitates the condensation of misfolded, ubiquitin-positive proteins and their degradation by autophagy, but the molecular mechanism of p62 signaling to the core autophagy machinery is unclear. Here, we show that disordered residues 326-380 of p62

Many diseases, including cancer, stem from aberrant activation or overexpression of oncoproteins that are associated with multiple signaling pathways. Although proteins with catalytic activity can be successfully drugged, the majority of other protein families, such as transcription factors, remain intractable

Cell-penetrating peptides (CPPs) are short protein segments that can transport cargos into cells. Although CPPs are widely studied as potential drug delivery tools, their role in normal cell physiology is poorly understood. Early during infection, the L2 capsid protein of
