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.
To better align with the essential requirement of quality management for the development and manufacture of Antibody and Protein used for IVD medical devices, GenScript has completed our registration to ISO 13485:2016 standard.

Learn MoreThe 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).

"I can attest to a very positive experience in working before protein expression scientists at GenScript. We tasked the GenScript team with challenging projects for the production of engineered proteins. We experienced frequent communication on progress, transparent data sharing, and open discussions on results and troubleshooting. The GenScript team demonstrated a high level of commitment both timelines and quality product delivery. I would highly recommend them for scientists seeking to advance their projects in a collaborative way."
"I have been delighted to use this outstanding service for the past five years. My experiences with the protein expression services have been exceptional, especially when working with mutated variants. The results have always been reproducible and of the highest quality, leading to excellent outcomes that were published in prestigious journals"
"GenScript has been very helpful for years. I consider them part of my lab. Rather than spending weeks and months expressing proteins, I get turn around on orders in a few weeks, and am never disappointed."
"I've had the privilege of collaborating with various service providers, but GenScript has consistently stood out in terms of reliability, quality, and innovation. Over the past few years, GenScript has become an indispensable partner in our research endeavors. Moreover, their custom protein services have been a game-changer. The purity and functionality of the proteins we’ve ordered have always met, if not exceeded, our expectations. This level of quality is crucial for the reproducibility of our experiments and the integrity of our results."
"Excellent quality and fast services, with a vast offer of molecular biology and protein/antibody products. The technical support is particularly helpful in finding the best solution for the specific experimental needs. Pricing is competitive and turnaround time is usually within the planned delivery date."
"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. "
