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)

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

Miniaturization of biochemical reaction volumes within artificial microcompartments has been the key driver for directed evolution of several catalysts in the past two decades. Typically, single cells are co-compartmentalized within water-in-oil emulsion droplets with a fluorogenic substrate whose conversion allows
