Protein Refolding Service

The technical service team of CD BioSciences has many years of experience in protein renaturation, and can obtain a large amount of high-purity, stable and soluble recombinant proteins (such as enzyme preparations, cytokines, etc.) from the E. coli expression system. Our inclusion body renaturation service has high refolding rate, and the recombinant protein before delivery will be tested by freeze-thaw experiments to ensure that the target protein is stable and soluble without any precipitation. CD BioSciences protein renaturation service will take into account the specific structure and physical and chemical properties of different protein inclusion bodies, and adopt a variety of renaturation methods. Our confidence is backed by our proprietary refolding technology, which includes high-hydrostatic-pressure techniques, small-molecule additives, and column-refolding methods.

Overall Solutions

Protein refolding services are provided along with our bacterial protein service packages upon request. Over 95% of the inclusion bodies can be solublized and refolded. We provide refolded protein at purity of 85% or greater. We provide you with the following service:

Service content Deliverable Cycle Price
Customers provide sequence information, CD BioSciences synthesizes and optimizes the target gene, subcloning, protein expression purification and renaturation. CD BioSciences delivers 3~5mg soluble protein, purity>90%, gene report, protein test report, project process report 4-6 week Inquiry
Customers provide plasmids and related experimental reports, CD BioSciences expresses and renatures and purifies the target protein We deliver 1~3mg soluble protein, purity>90%, project process report, protein inspection report 2-3 weeks Inquiry


1. The delivered recombinant protein has a concentration above 0.2 mg/mI and is stored in common buffers (Tris, PBS, etc.), and protein freeze-drying services can also be provided.

2. In the all-inclusive service, CD BioSciences provides free codon optimization service to ensure maximum protein activity.

3. If customers have requirements for protein expression, we can provide soluble protein of 10mg and above, and pack them according to customer requirements.
