KBI has redefined what it means to have an optimal expression strain.


10+ years of therapeutic protein development rolled into one platform.

The KBI PUREplatform™ starts in cell line development (CLD) with a proprietary strain platform that includes unique substrains, designed specifically to quickly feed upstream process development and late-stage manufacturing with preestablished process elements.

E. Coli Expression

Across Protein Types

Part of Optimized CLD

State-of-the-Art IP

Just One way KBI is Doing More with Microbes.

A platform, a premium strain, and cutting-edge screening together yield optimal protein expression that is uniquely tailored to each project.

A New Host Strain-Plasmid Combination

A New Core of CLD and Microbial Optimization 


At KBI Biopharma, our PUREplatform™ is everything you need to make a protein. Containing plasmids, strains, media, and a fermentation process that all fit together into a service package, catered to your needs. This new core completes our microbial offering from premium cell line development through to late-stage and commercial manufacturing.

  • Features our PUREcoli™ cell line, our proprietary high-producing E. coli cell line, expertly paired with PUREplasmids™ and PUREmedia™ available in 8, 48, and 96 screening packages
  • Leverages 10+ years of E. coli-based optimization and upstream development
  • Designed for secreted proteins, including antibody fragments (FABs), inclusion bodies (IBs), and soluble intracellular molecules
  • Robust fermentation conditions that scale from high-throughput 1 mL microfermentations
  • Built for small- and large-scale cGMP manufacturing
  • Reduces cost of goods, improves efficiencies, and compresses development timelines
  • FDA/EMA Inspected Facilities
  • Well-versed in first-in-human (FIH) studies, late-stage manufacturing, and commercialization

Strain development was just the start of our mission. To support biopharmaceutical development and fermentation production, our platform targets product quality, safety, and titer across proteins and at scale.
