cGMP Cell Line Development
The development of cell lines is the starting step of the chemical manufacturing and CMC phases and is the core of the biomanufacturing process. High yield and quality cell lines provide a solid foundation for a successful biopharmaceutical production process and determine the quality of the final product. Creative Biogene is committed to providing efficient cell line development services based on our extensive experience in cell line development and leveraging our advanced cGMP technology platform. We specialize in providing all services from vector construction to screening of stable and highly expressed cell lines. These cell lines are GMP compliant and can effectively help our customers to successfully develop and produce biologics such as biosimilars, enzymes, cytokines, antibodies, vaccines and other recombinant proteins.

Cell Line Development Process at Creative Biogene
Creative Biogene's experienced scientific team provides a standardized process for cell line development, with the entire development cycle typically taking 12-18 months. We can meet the individual demands of our clients at any stage of cell line development, thus ensuring successful research cell banks (RCB), master cell banks (MCB) and working cell banks (WCB). Once the cell line development process is complete, we generate high-quality cell libraries that can be used for further process development and optimization, as well as high level production, thus helping our clients save time and obtain high-quality custom cell lines.
