WebJun 23, 2015 · Mixed cryoprotectants have been developed for the solubilization of ligands for crystallization of protein-ligand complexes and for crystal soaking. Low affinity lead compounds with poor solubility are problematic for structural studies. Complete ligand solubilization is required for co-crystallizat … WebCo-crystallization; Compared with soaking, protein-ligand co-crystallization usually requires more resources and time. However, it is often the best option when obvious conformational changes or crystal packing preclude other approaches. The requirement to optimize crystals for each complex makes this method resource- and time-intensive. WebMay 28, 2024 · Soaking offers various advantages over co-crystallization, e.g. small samples and high-throughput experimentation. However, this method has disadvantages, such as inducing mechanical stress on crystals and reduced success rate caused by low affinity/solubility of the ligand. phillips stick on soles
