Purification
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
Case Study: Using Selective Washes to Solve a Purification Issue
By leveraging experience gained from developing processes for over 75 biomolecules, KBI has perfected standard approaches for developing processes for various classes of proteins, including monoclonal antibodies.
This experience has also allowed KBI to develop a toolbox that promptly resolves unique protein purification challenges.
Case Study: A Comparison of Multimodal Chromatography Resin
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.
Having integrated process development and analytical development teams ensures a broad perspective to achieve product quality goals for each program.
