ESTABLISHMENT OF AN ULTRA HIGH-THROUGHPUT PROTEIN PRODUCTION PLATFORM (ULTRA 96) FOR EARLY STAGE IN VITRO STUDIES

Abstract Proteins are known as the building blocks of life which play many critical roles in the body. In early stage drug discovery, numerous μg to mg scale high quality proteins need to be produced for in vitro functional studies and therapeutic evaluation, including antigens, monoclonal antibodies (mAb), bispecific antibodies (bsAbs) as well as other Fc fusion proteins. High-throughput production (HTP) of various proteins with high quality in very short time is a big challenge in industry. Here we present how WuXi Biologics has created a powerful ultra HTP protein production platform (termed as “Ultra 96”) that can automatically produce proteins within 3 weeks with one step purification at 1~3mL expression scale by using 96 and 24 well DWP. High titer of expression, high quality of products, short timeline as well as low cost make “Ultra 96” a robust platform which can empower our clients and dramatically accelerate their early stage drug discovery projects.
