Large-scale Protein Expression and Purification Service

With the rapid growth of the protein drug market and recent advances in proteomics, the supply of large quantities of pure, active proteins has become essential for the production of protein drugs and to the development of drug assays and research methods. GenScript is fully equipped to meet this need for large-scale protein expression and purification. Our versatile and reliable protein expression system, which includes fermentors, wave mixers, and bioreactors, combined with our large-scale purification service, allows GenScript to provide its clients in both the public and private research sectors, academia, and all levels of the pharmaceutical industry with protein orders as large as one kilogram. GenScript has delivered more than 500 proteins, including 300 grams of protein on a single project.
