Glycerol is used both in sample preparation and gel formation for polyacrylamide gel electrophoresis. Glycerol (5-10%) increases the density of a sample so that the sample will layer at the bottom of a gels sample well.
Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. Glycerol acts as a cryoprotectant and prevents formation of ice crystals and prevents cell damage. Glycerol is useful in a variety of applications, glycerol is used as a solvent, plasticizer and humectant.
