If you agree that your CHO-derived biologic shouldn’t be subject to development constraints imposed by others, break free with Gibco Freedom Cell Line Development Kits. Gain commercial licensing that’s simple, flexible, and without royalties.
Gibco Freedom kits, developed in collaboration with ProBioGen AG, contain all the components for beginning-to-end cloning and expression, within a short development time (<6 months from gene of interest to clone). Contact us about our 40% discount program on the ExpiCHO-S kit or CHO-DG44 kit today.
Freedom Kit benefits include:
*When using Freedom ExpiCHO-S Kit as recommended. Results may vary, based on process conditions.
Your Freedom kit includes support from the Gibco Field Application Scientist (FAS) team—experts in biopharmaceutical processes and the use and applications of Gibco products and services. The FAS team has broad experience in cell culture, process characterization, scale-up, analytics, product development, process optimization, and tech transfer. Guidance and step-by-step support can be provided to you throughout the cell line development workflow.
