1. Protein refolding
Overproduction of proteins in E.coli can cause the formation of inactive, misfolded and insoluble protein aggregates. GenScript provides proprietary refolding technology to solve this problem. A case study shows that over 95% of inclusion bodies are solublized and refolded. The purity of the refolded protein is more than 85% and is delivered in customized buffer.

2. Tag removal
Presence of epitope tag in recombinant proteins may result in changes in protein structure, toxicity, and loss of bioactivity. To avoid these problems, tag removal after protein expression is requested by some customers as an additional service. Shown below is protein that is cleaved by SUMO protease and successfully isolated. Recovered target protein is more than 90% pure and 80% tag free.

Customer Testimonial
"GenScript provides fast, professional protein synthesis services at very reasonable prices. By making it cost-effective to outsource protein production, GenScript has made it possible for my lab to focus on our own area of expertise and get more research done. The detailed planning, updates, and reports that GenScript provides all of the quality control that one could ask for. I strongly recommend GenScript's protein production service."
— Dr. Barry Bradford, Kansas State University Department of Animal Sciences & Industry

Protein sequences are subject to pre-project analysis. Exclusions are applicable for membrane proteins and toxic proteins.
For eligible proteins, a minimum of 3mg soluble protein with 75% or 85% purity will be delivered to customers. The protein services will be free of charge if GenScript's evaluation reveals that the expression level is insufficient to eventually obtain 3mg of purified protein. To increase the expression level of your protein, gene optimization using our OptimumGene™ technology is recommended. Up to 3 fusion tag(s) may be tested to increase the expression level and solubility of the protein and are applied for protein production and purification. Fusion tags may be removed by introducing an optional protease cleavage site between the tag and the target protein (note: tag removal service is offered at extra cost) . Insoluble proteins will be subject to refolding using our FoldArt™ technology at no additional fee.
* Customized protein services apply if the target protein is greater than 100KDa
