WebOct 9, 2009 · Abstract. The stability of proteins in aqueous solution is routinely enhanced by cosolvents such as glycerol. Glycerol is known to shift the native protein ensemble to … WebGlycerol is hygroscopic in nature and is soluble in water owing to its three hydrophilic alcoholic hydroxyl groups. It can form both inter- and intramolecular hydrogen bonds, …
WebJan 18, 2015 · This allows them bind both to the hydrophobic sites on your protein and simultaneously hydrogen bond with the surrounding water of your buffer. This promotes protein solubility, and prevents aggregation and heat-induced denaturation. Commonly used chemical chaperones include: Glycerol. Trehalose. Mannitol. Maltose.
