Cell Culture Process Development

As a leader in the field of immunotherapy, Creative Biolabs has gained extensive experience developing mammalian and microbial production cell lines. The discovery experience companied with our advanced analytical capabilities enables us to identify and select clones that meet your product’s specific parameters and characteristics. After selecting the most appropriate clones, we optimize cell culture conditions to develop a high productivity cell line tailored to your specific product quality targets and desired productivity level, which is designed for robust, scalable manufacturing.

Technical transfer for cGMP production for worldwide IND submissions.

Perfusion and concentrated fed-batch platform

High viable cell density and viability,
For perfusion: long term steady-state operation and stable productivity and quality,
For concentrated fed-batch: quick adoption from fed-batch with high harvest product titer and improved quality,
From bench top scale-down model to cGMP manufacturing production.

Expression Platform

We have developed a series of proprietary expression systems. These robust and scalable expression platforms have been used extensively to create many production cell lines. It accelerates development of cell lines for further production by using robust procedures and chemically defined media and feeds, to produce high levels of recombinant protein with a short timeline.

Product Quality Optimization

To optimize various product quality attributes, we have established a comprehensive series of approaches including, but not limited to.

Aggregation control,
Charge variant control,
Glycosylation optimization,
Sialic acid content optimization,
ADCC/CDC activity optimization .

Each step in the upstream process impacts the quality, purity, and quantity of the manufactured protein. At Creative Biolabs, we have developed various mammal -, bacteria and yeast-based cell culture developments in the last decade, giving us the insight necessary to identify and optimize upstream parameters that are critical for achieving a high-quality, cost-effective biomanufacturing process.
