WebJul 13, 2006 · The ability of glycerol/water mixtures to inhibit ice crystallization is linked to the concentration of glycerol and the hydrogen bonding patterns formed by these solutions. At low glycerol concentrations, sufficient amounts of bulk-like water exist, and at low temperature, these solutions demonstrate crystallization. WebDec 12, 2016 · Glycerol is a weak ligand for Gal-3 , such that high affinity ligands should readily displace glycerol. This approach has been suggested as a good method to exchange ligands with Gal-3. Here, we observed that the lactose displacement time with glycerol in Gal-8 N-terminal CRD crystals was only ~1 min, much shorter than that …
