Glycerol (50%)

Glycerol is a sugar alcohol commonly used in laboratory applications. When aqueous, 50% Glycerol has low activity and a very low freezing temperature, allowing for effective storage and preservation of enzymes. It has a high relative density, aiding in sample loading for electrophoresis, and helps facilitate sample migration and resolution. The molecular structure of glycerol also allows for sample stability through hydrophilic-lipophilic balances, protecting target enzymes from degradation.
