General description

BL21(DE3)电转感受态细胞是第一个在相同细胞中实现高效克隆和高水平蛋白质表达的细胞。
克隆效率比其它 BL21 细胞制剂提高了 25-1,000 倍,这对于构建复杂的表达文库至关重要。

基因型

F – ompT hsdSB (rB- mB-) gal dcm (DE3)

Features and Benefits

BL21(DE3)电转感受态细胞(>5 × 109 cfu/μg)前所未有的转化效率消除了将质粒从克隆菌株转移到表达菌株的需要,从而为典型的克隆和表达实验节省了数天的工作时间。

Under high light, oxygenic photosynthetic organisms avoid photodamage by thermally dissipating absorbed energy, which is called nonphotochemical quenching. In green algae, a chlorophyll and carotenoid-binding protein, light-harvesting complex stress-related (LHCSR3), detects excess energy via a pH drop and serves as

We follow the cotranslational biosynthesis of three multispanning Escherichia coli inner membrane proteins in vivo using high-resolution force profile analysis. The force profiles show that the nascent chain is subjected to rapidly varying pulling forces during translation and reveal unexpected

The ClpXP degradation machine consists of a hexameric AAA+ unfoldase (ClpX) and a pair of heptameric serine protease rings (ClpP) that unfold, translocate, and subsequently degrade client proteins. ClpXP is an important target for drug development against infectious diseases. Although
