Cell Line Development

Stable cell line shows a great capacity in many fields, especially in immunotherapy (including production of recombinant protein and monoclonal antibody), drug screening and gene function study. After years of hard work, Creative Biolabs can provide a stable cell line development service as per your requirement. Our cell line development service includes cell line construction, process development, cell banking and analysis, etc.

End-to-end process of cell line development.

Cell Line Construction

A stable cell line can reduce the production costs of biopharmaceuticals with high efficiency of productivity and desired critical quality. Our strategy is to identify highly productive clones. In our fed batch fermentation platform process, they are also selected to grow well in suspension culture, which can save time in the later stage of the production process. We offer a variety of approaches to cell line construction that can be chosen according to your priorities in terms of timelines, yield optimization and potential risks. Our team will perform cell line development service and provide you with reliable options to determine the best type to fit your project requirements. We are able to offer customized combinations according to your target recombinant proteins.

Processes of Cell Line Development:

We start with DNA or protein sequences provided by our clients, and eventually offer well-characterized, high-yielding, and stable monoclones.
