Solid-phase refolding methods are advantageous since they facilitate both separation of solid additives from the refolded protein and recycling of the additives. beta-Cyclodextrin-acrylamide copolymer hydrogel beads were used as a matrix for detergents in solid-phase artificial chaperone-assisted refolding and improved the yield of lysozyme (up to 65%) and carbonic anhydrase B (up to 80%), compared with conventional solid host matrices.
