Large-scale Protein Expression and Purification

CD BioSciences has a mature protein expression system and advanced protein expression technology. A large amount of protein is a prerequisite for scientific research, but there are still certain difficulties in large-scale protein production. We provide large-scale recombinant protein preparation services including: protein fermentation, high-density fermentation technology and process optimization.

CD BioSciences has various types of fermentation tanks, bioreactors, and protein purification systems, which can provide recombinant proteins in milligrams to grams. Customers can choose the appropriate expression system and fermentation program according to their needs.

Service process

Gene optimization: gene sequence is a key factor in determining the success or failure of protein expression

Optimization items include: mRNA structure, rare codons, ribosome binding sites, etc.

Optimization of expression conditions: Optimization of protein expression conditions, including temperature, inducer, OD and other factors affecting protein expression, has achieved higher cell culture density and protein expression during subsequent fermentation.

Large-scale fermentation production: divided into ordinary protein fermentation and high-density fermentation, including protein fermentation process optimization, temperature, pH, and dissolved oxygen feeding methods.

Protein purification: After obtaining a large amount of protein expression bacterial paste, we can provide corresponding protein purification services (optional), a variety of protein purification methods to choose, and finally deliver the protein of the purity required by the customer.
