With current advances in technology and biopharmaceutical research, cell line development (CLD) has become a prominent process in many application areas. One of these areas would be the development of biotherapeutics, including a variety of monoclonal antibodies, vaccines and biologics. The development of such new medical treatments has seen a sharp increase in demand for better quality and safety standards. In order to meet the increasing demand for these types of products, researchers rely on different mammalian expression-based systems, with CHO cells being the most popular system for large-scale\nindustrial culturing.<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Throughout the use of cell-based assays, researchers have been screening different clones in order to increase productivity of biopharmaceuticals. The manual screening methods traditionally used for CLD are time consuming and labor intensive. As such, there is a great demand for high-throughput, automated solutions for better processes that follow GMP and legal safety standards while also drastically reducing the production timeline. The proposed workflow using our UP.SIGHT, C.NEST\n and F.QUANT helps to streamline and optimize your research to generate high-producing cell lines with a probability of clonal derivation of >99.99%.<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Based on early regulatory guidelines released by the U.S. Food and Drug Administration (FDA) and others, the production cell line of recombinant products is to be derived from a single cell in order to minimize population heterogeneity as well as facilitate isolation and subsequent selection of high-producing clones.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

After single-cell cloning, clones exceeding a certain confluency threshold are selected for suspension culture in order to expand cell numbers. Traditional workflows for cell culture happen under static conditions, taking up several weeks of work before viable clones are transferred to shaken deep well or 24-well plates. After additional cultivation, selected clones are then transferred to larger volumes and finally to shake flasks or mini bioreactors. Hence, during the first weeks after cloning, cells are cultured under static conditions, which do not match the culture environment the cells experience in later stages of the process and during production. Our innovative microbioreactor platform, the C.NEST\u00ae, was developed to enable suspension culture early in the CLD process. With the C.NEST platform, cells are kept in a more suitable environment thanks to the circulating flow of medium, thus maintaining homogenous levels of nutrients and dissolved oxygen.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
