Extensive, Diverse Molecule Support

Across a wide range of molecules, including mAbs, bispecifics, Fc fusions, and more

At KBI Biopharma, our SUREtechnology Platform has successfully supported the expression of a wide range of molecules for biopharmaceutical and vaccine development, coupled with robust verification to assure biosafety and efficacy. Across 300+ programs for 200+ global customers, we have supported the development of:

  • 150+ monoclonal antibodies (mAbs)
  • 40+ bispecific antibodies
  • 35+ Fc fusions
  • 40+ non-IgG molecules, including vaccines, blood factors, hormones, and enzymes, among others


Not just another CLD platform

Our unique and patented technology enables faster, safer, and more efficient biopharmaceutical development.

Embedded in our transfection vectors are patented chromatin modifiers that unwind the DNA at the site of transgene integration, boosting transcription and therefore increasing recombinant protein expression. These epigenetic elements are key to obtaining the highest - and most reproducible - gene expression levels across protein types.

Furthermore, we believe in full transparency and robust verification. To that end, our extensive genomic characterization and monoclonality assessment services assure the biosafety and efficacy of developed products.
