Efficient isolation of soluble intracellular single-chain antibodies using the twin-arginine translocation machinery.

Abstract excerpt

One of the most commonly used recombinant antibody formats is the single-chain variable fragment (scFv) that consists of the antibody variable heavy chain connected to the variable light chain by a flexible linker. Since disulfide bonds are often necessary for scFv folding, it can be challenging to express scFvs in the reducing environment of the cytosol. Thus, we sought to develop a method for...
