제목 Cell-free synthesis of functional cell-penetrating scFv in a cell-free protein synthesis system derived from Escherichia coli
초록 In this study we attempted to express the scFv antibodies that had been engineered to penetrate into the cells and give signal through split GFP complementation. Cell-free protein synthesis system provides a high accessibility to the translational mechanism, thereby providing optimal environments to increase the productivity and solubility of scFv. To assist the formation of correct disulfide bonds, we have changed redox conditions of the cell extract and reaction mixture using GSSG/GSH redox buffer. To increase the solubility, we used a cell extract enriched with DsbA, DsbC, FkpA and SurA. We also used the leader sequence ubiquitin,in front of the target scFv and achieved a high level expression of functional scFv antibodies. The functionality has confirmed by reading the fluorescence signal of transfected cells in a black plate assay
