Interactive Crystallization
a true milestone in crystallization of biological macromolecules
Interactive Crystallization
Adjusting crystallization conditions based on real time monitoring of molecular interactions.
Cryo protection
Cryo protection often leads to an osmotic shock of a crystal since mother liquor is significantly changed with osmotic active substances.
High degree of cross-linking
Crosslinking crystals to a high degree can be challenging as the initial concentration of such reactive agents must be carefully considered. In addition, side reactions can occur which negatively affect the degree of crosslinking. Picotitration of fresh crosslinker provides shock free long term crosslinking.
Nanocrystal Production
A common and non-destructive approach to producing nanocrystals is to avoid interphases by picolitre titration. The resulting crystals can be as small as crystals just at the critical radius.
