Antibody Expression of scFv and VHHs
We can prepare antibody expression for VHH and scFv antibodies in E. coli and mammalian cells, and the antibodies will have both an N-terminal FLAG and C-terminal HIS tag. The yield will average 100-200 ug for small-scale production (usually higher for VHH) that can be scaled up for increased yields. The antibodies are purified via the HIS tag by Ni-NTA chromatography or using the FLAGG tag and generally are about 90%+ pure. We can also incorporate alternative tags.
Both scFvs and VHHs can be engineered into a traditional antibody format (see Antibody Engineering for more information) by fusing onto a Fc backbone. Antibody generation produces these antibodies at small scale in mammalian expression systems with resulting yields of 200-400 ug and also are purified via protein A.
We can readily scale up expression or increase yield of antibodies if desired.
