Solid-phase refolding using novel hydrogel beads enhances protein refolding yields. This method improves recovery for lysozyme and carbonic anhydrase B, offering a more efficient protein refolding solution.

Area of Science:

  • Biochemistry
  • Biotechnology
  • Materials Science

Background:

  • Solid-phase refolding offers advantages in additive separation and recycling.
  • Artificial chaperone-assisted refolding is crucial for protein recovery.
  • Developing efficient solid matrices is key for improved refolding yields.

Purpose of the Study:

  • To investigate the efficacy of beta-cyclodextrin-acrylamide copolymer hydrogel beads as a solid-phase matrix for artificial chaperone-assisted protein refolding.
  • To compare the refolding yields obtained using this novel hydrogel matrix with conventional solid host matrices.

Main Methods:

  • Preparation of beta-cyclodextrin-acrylamide copolymer hydrogel beads.
  • Utilizing the hydrogel beads as a matrix for detergents in solid-phase refolding.
