High-yield expression of periplasmic single-chain variable fragments by solid Escherichia coli cultures

High-yield expression of quality antibody fragments is indispensable for research and diagnosis. Most recombinant antibody fragments are expressed in Escherichia coli using liquid cultures; however, their yields and quality are often poor. Here the authors expressed a single-chain variable fragment...

520 |a High-yield expression of quality antibody fragments is indispensable for research and diagnosis. Most recombinant antibody fragments are expressed in Escherichia coli using liquid cultures; however, their yields and quality are often poor. Here the authors expressed a single-chain variable fragment in E. coli cultivated on the wet surface of a solid support. Compared with a liquid culture, the authors obtained 2.5-times more single-chain variable fragments with membrane-cultivated E. coli. This method has two important advantages: it enables high yields of periplasmic single-chain variable fragments compared with liquid culture and offers simple and rapid expression and extraction
