CHO Stable Cell Line Development
Curia provides stable CHO cell line development services for diagnostic or therapeutic products.
Developed from the CHO-K1 parental cell line, Curia offers the CHO-GSN™ stable cell line expression platform for the production of proteins and antibodies. CHO-GSN™ is a glutamine synthetase (GS) knockout cell line for the generation of a research cell bank (RCB) and future use as a manufacturing cell line for commercial products. With multiple RCBs used for programs at the clinical stage, this platform offers clients a cell line with lineage documentation and a commercial use license for commercialization (royalty-free option available).
Curia provides the CHO-GSN™ platform as a CHO stable cell line development service using its proprietary knockout cell line, custom stable expression vectors, and glutamine synthetase (GS) selection technology platform.
