Cell Line Development
Cell Line Development
We make it our mission to deliver stable cell clones and pools that consistently generate high yields and high- quality products of antibodies and recombinant proteins for growing biopharmaceutical industry. KCell Biosciences has extensive experiences in protein expression in mammalian cells and has established many proprietary subtypes of CHO cells to serve our mission and meet our customer’s demands.
Proven experts in Process Development
- We have been successful in delivering high quality recombinant proteins and antibodies for more than 130 contracted projects
High Efficiency and High Yield
- By integrating media formulation and process development, KCell Biosciences offers clients a more specialized approach for generating cell lines that produce the most optimal yield, quality, and stability of recombinant proteins or antibodies. Using 14-day fed-batch process, we achieve protein yields of 3 - 6 g/L, and even higher in some cases.
Documentation to Support Regulatory Filing
- KCell Biosciences provides all customers with documentation of single cell imaging, cell division, and cell growth rates during the single cell cloning process to demonstrate monoclonality for regulatory filing.
High Throughput Selection and Fast Delivery
- Integrated media formulation and process development platform enables KCell Biosciences to optimize transfection efficiency, characterize individual clones, and identify the best single cell clones for cell line development within only 3 - 5 months.
One-Stop Solution : Sequence to Commercialization
- KCell Biosciences’ stable cell line development service also offers molecular cloning of a gene sequence into an expression plasmid and media optimization services in addition to providing our customers with high-yield single cell clones. Our media optimization service enables us to be more efficient at process development and scale-up for your project needs.
