Abstract
We have investigated different dialysis strategies for the refolding of recombinant streptavidin, and present a novel dialysis setup featuring gradual dilution dialysis and continuous protein feeding into a dialysis sack. A denaturing dialysis buffer is exchanged gradually by dilution with refolding buffer and it is demonstrated that the refolding yield can be increased from 45 to 75% by lowering the dilution rate. In addition, continuous feeding of protein to the dialysis sack increases the yield by 5 to 10%. The principle of gradual dilution dialysis is amenable to stringent regulation and we suggest it to be applied for other insoluble protein targets.Mesh:
