We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. Glycerol is non-toxic, biodegradable, and comes from a renewable feedstock, thus aligns with "Safer Solvents and Auxiliaries", "Use of Renewable Feedstocks", and "Design for Degradation".

Application: 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 gel's sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component.
