Immobilized β-cyclodextrin

Immobilized β-cyclodextrin is designed to allow refolding of recombinant proteins that were aggregated or

formed inclusion bodies when expressed in the genetically engineered cells. The refolding of misfolded

proteins is adapted from GroE chaperone refolding mechanism. The misfolded proteins or inclusion bodies

are solubilized with detergent such as Triton X-100 in the first step to avoid protein aggregation. In the

following step the detergent treated protein is passed through immobilized β-cyclodextrin agarose

preequilibrated with refolding buffer. Cyclodextrin strips away the detergent allowing proper refolding of

proteins.

  Do not use azides.

• Physical stability: Volume variations are negligible for changes in pH or ionic strength

• Storage temperature: 4°C

• Supplied as 50% slurry in 20 % ethanol

Application;

• Immobilized β-cyclodextrin is designed to allow refolding of recombinant proteins that were aggregated or

  formed inclusion bodies when expressed in the genetically engineered cells.
