Recombinant Protein Expression Service

Protein expression is almost universally used by research groups for a variety of purposes. There are three main expression systems, Bacteria, Baculovirus/insect, and Mammalian cells, available today giving researchers enough choice to find the best system for their specific application. As a leading provider of a comprehensive suite of recombinant protein and antibody services across different expression systems, GenScript seeks to partner with scientists worldwide to accelerate scientific discovery. Our proprietary GenSmart™ Codon Optimization and newly launched TurboCHO™ expression platform ensure the delivery of high-yield and purity products in a flexible, cost-effective manner in the least amount of time. Our expert scientists and dedicated technical account managers are invested in helping to maximize the success of your research projects and will guide you every step of the way.

Expression System Comparison

The features of a target protein inform which expression system is best suited for the expression of that protein, and it is important to identify the correct system for protein expression based on these criteria. These specific features include sequence and structure as well as activity, function, folding, and post-translational modifications (PTMs).

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.
