WebJan 20, 2014 · Whereas in solution refolding, the motion of protein molecules is somewhat restricted by the column particles and hence aggregation can, in principle, be greatly reduced. In such a simple system, however, concentration gradient between the load and the column may be too steep to allow sufficient time for the unfolded scFv to slowly refold. WebThe compactness of the protein chain continues to evolve at higher SDS concentrations according to single-molecule studies, though the protein remains completely denatured on the tertiary structural level. SDS denaturation can be reversed by addition of nonionic surfactants that absorb SDS forming mixed micelles, leaving the protein free to refold. in store leather recliners
