Expert purification process development for biotherapeutics

Developing Purification Process to Support New Biologics

Applying Deep Knowledge and Experience to the Science and Practice of Biopharmaceutical Drug Development

 

By leveraging the experience gained from developing processes for more than 75 unique biomolecules, KBI has perfected standard approaches for process development across various classes of proteins, including monoclonal antibodies.

KBI Biopharma has extensive experience developing purification processes for a wide variety of biotherapeutics, including:

  • Monoclonal antibodies
  • Bispecific antibodies
  • Enzymes
  • Fc fusion proteins
  • PEGylated proteins
  • Complex glycoproteins

This experience has also allowed KBI to develop a toolbox that promptly resolves unique protein purification challenges.

KBI’s robust protein characterization capabilities, including conformational and structural analyses via biophysical techniques and mass spectrometry, provide “fast insight” into a client’s unique product, enabling a development strategy that accelerates timelines and reduces risk.
