As the name suggests, Chinese hamster ovary cells, or in short CHO cells are derived from the ovary of a small rodent called the Chinese hamster. Due to their similarity to the human cell system, CHO cells are used in biological and medical research, primarily such as genomic and chromosome studies, toxicity assays, and nutrition and gene expression. CHO cells are by far the most commonly used production cell lines in the pharmaceutical industry with a safety profile established over 20 years.

Creative Bioarray provides a cGMP-compliant CHO cell bank by following the industry-standard cell bank system to help our customers worldwide. Our platform is equipped with cGMP production facilities, and extensive technical and regulatory expertise to support our clients' research. We also have a wealth of experience and knowledge and will advise on the most appropriate and cost-effective testing strategy to meet scientific and regulatory requirements.

Our Cell Services Cover the Complete Lifecycle of a Cell Bank

• Testing of developed cell lines, including CHO-K1, DXB11, S, DG44 prior to bank construction.
• Cell banking for master cell banks (MCB) under cGMP conditions. In the industrial process, we use serum-free media strictly according to recent regulations.
• After the establishment of an MCB, a working cell bank (WCB) is constructed from the MCB.
• Complete validation and release of MCB and WCB in compliance with national regulatory requirements.
• Long-term storage of cell banks under cGMP management.
