Crystallization
Crystallization — The process of forming an ordered crystalline solid from a solution, required for X-ray crystallography structural determination of peptides.
What Is Crystallization?
Crystallization is the process of forming an ordered solid from a solution. In peptide research, crystallization serves two purposes: growing single crystals for X-ray crystallography structural determination, and crystallizing peptide APIs for pharmaceutical manufacturing (improving purity, stability, and handling).
Methods
- Vapor diffusion: Hanging/sitting drop. Standard for protein/X-ray crystals
- Insulin crystallization: Zinc-insulin hexamer crystals used in pharmaceutical manufacturing since 1926
- Screening: Sparse matrix screens (Hampton Research) test hundreds of conditions simultaneously
Frequently Asked Questions
