Cell Culture Process Analytical Development

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 ambr15 to 2000L scale. In depth understanding of the impact of agitation, aeration, and working volume at each scale has allowed us to tech transfer in wide variety of processes very successfully.

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

The KBI CCPD team has experience with over 15 different mammalian cell line vendors. The nuances about the different cell line platforms allows 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.
