Cell Culture

Cell culture process development supporting the full development cycle

Unwavering Customer Focus and Situational Flexibility

From Early-Stage Discovery to GMP Manufacturing


Our unwavering customer focus and situational flexibility combined with a solid scientific base enable us to be the ideal partner for our clients.

Cell culture process development activities at KBI cover the full development cycle, from supporting early-stage discovery efforts through small-scale protein production to fully-integrated, comprehensive process development programs leading to cGMP manufacturing to process characterization and scale-down validation studies.

The KBI team has worked with protein production processes at all scales, from laboratory, pilot, and clinical scales to commercial scales up to 2000L. We have characterized mixing conditions in bioreactors from Ambr® 15 to 2000L scale. An in-depth understanding of the impact of agitation, aeration, and working volume at each scale has allowed us to successfully tech transfer in a wide variety of processes.

KBI has been a pioneer in integrating new and cutting-edge technologies into our process development platform. For example, the use of high throughput miniaturized bioreactors and associated analytics for process optimization and characterization intensified upstream process, and targeted optimization of product quality attributes are services offered at KBI.

The KBI upstream PD team has experience with over 15 different mammalian cell line vendors. The nuances of the different cell line platforms allow us to develop high-productivity, robust, and scalable processes within an expedited timeline. In addition to standard mAbs, KBI has extensive experience in developing Fc-fusion proteins, bi-specific antibodies, growth factors, enzymes, vaccine glycoproteins, PEGylated proteins, and other glycoproteins.
