At Aragen, we work closely with clients to deliver customized therapeutic cell line development. We specialize in difficult to express proteins, and our mammalian host cell lines are primarily developed in Chinese Hamster Ovary (CHO) cells to produce recombinant protein products of interest. Most clients leverage the decades of experience we have with our inhouse CHO-DG44 platform, which delivers a royalty free, low risk option for the scalable manufacture of proteins within a cGMP environment. We also have significant expertise in multiple mammalian expression platforms, including CHO-S, CHO-GS, and Sigma’s CHOZN.
