Usage:is useful in a variety of applications, glycerol is used as a solvent, plasticizer and humectant. In polyacrylamide gel electrophoresis, glycerol is used in sample preparation and gel formation. At a concentration of 5-10%, glycerol is used to increase the density of a sample so that it will layer at the bottom of a sample well. Additional uses include as an aid in casting gradient gels, a protein stabilizer and storage buffer component.
