Peptide Crystallization

Peptides present increased complexity for crystallization due to their large size, structural flexibility, and diverse functional groups, which lead to a much narrower crystallization operating range compared to small molecules. Compounded by a high risk of gelling, fibrillation and aggregation, these challenges often result in low-purity outcomes and elevated residual solvent contents. Even when solids are recovered, they are frequently isolated as amorphous forms, which pose significant challenges in handling, production and downstream formulation steps. These complexities necessitate innovative approaches to ensure the successful crystallization of peptides while maintaining their structural integrity and therapeutic efficacy.

Specialized Peptide Crystallization Capabilities

At Cambrex, we recognize the critical role of crystallization in overcoming the inherent challenges of peptide manufacturing. In parallel with our investment in custom peptide synthesis technologies, we have developed cutting-edge peptide and protein crystallization capabilities to address these complexities.

Our proprietary screening platform is specifically designed to discover and optimize crystalline forms of peptides and proteins. This platform leverages advanced techniques to identify conditions that promote crystallization, even for highly complex or aggregation-prone peptides. By integrating crystallization into the manufacturing process, we offer clients a range of benefits that address key challenges in peptide production:

  • Significant impurity rejection
  • Improved processability
  • Reduced hygroscopicity
  • Increased stability
  • Control of aggregation & gelling
  • Full structural determination
  • Cost advantage when compared to column chromatography methods for purification

Our approach to peptide crystallization is rooted in science-first innovation and a commitment to solving the most complex challenges in development and manufacturing. It’s not just a manufacturing step — it is a transformative process that enhances the quality, stability and efficiency of your peptide therapeutics.
