General description

Obtained from oils and fats as a biproduct in the manufacturing of soaps and fatty acids (absorbance: ≤0.07 at 260 nm; ≤0.02 at 280 nm).

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.
