Cell Line Development System Commercial License

GenScript ProBio is now licensing the CHOK1-GenS cell line development system to biopharma companies for commercial use. Contact us for more information!

GenScript ProBio has 12 years of experience in mammalian cell line development, and is one of the earliest companies getting the CHO-K1 - CHO commercial license for commercial use and sublicense agreement from ECACC.

After serum-free suspension adaption and characterization, GenScript ProBio acquires the host cell for CHOK1-GenS cell line development system without chemical modification. In together with the high-expression proprietary pGenHT 1.0-DGV vector, the yield titer can reach an average of 4.35g/L , up to 8.70g/L

GenScript ProBio is experienced with 300+ cell line development projects, and the CHOK1-GenS system has been used in 30+ CMC&CMO projects in which 5 has got IND approvals.
