Aragen Bioscience excels in providing a range of specialized services to the Human health and animal health industries. Our scientists and staff play a crucial role in accelerating the biologic drug development process. We offer high-quality and efficient solutions to our clients in the following areas.

Cell Line development for expressing complex biologics on our validated CHO-DG44 and CHO-GS cell lines.
Royalty-free RapTr 2022 platform
Biosimilar development support for Human and Animal health industries.
Robust upstream and downstream process development
Process consistency and scalability with bioreactors (1L, 5L & 10L).
Single Use Bioreactors (50L and 250L).
Optimization of manufacturing scale-up with tight control and robust product characterization.
Building GMP 2 x 500L SUB manufacturing facility for Drug Substance bulk.

Aragen Bioscience’s scientists have perfected cell line process combined with modern laboratories, a clear strategy, working closely with the clients with collaborative spirit to deliver best titers, greater superior cell viability, while reducing cost and time. For example, our RapTr 2022 CLD platform offers a 33% reduction in CLD timelines and increased titres up to 6g/l. This royalty-free platform now accelerates the process from DNA transfection to Research Cell Bank (RCB) to 18 weeks. The RapTr 2022 CLD services include the proven CHO-DG44 and CHO-GS cell lines and proprietary vector combinations with an innovative clone selection process for standard monoclonal antibodies.
To illustrate, our new GS platform that used Aragen Bioscience’s proprietary GS Vector for Humira development showed enhanced stable bulk pool (BP) ~700mg/L, single cell clone (SCC) from BP up to 2g/L with clones showing stability up to 60 days, and mini pool (MP) generated up to 4.2g/L.
