Purity: 99.0-101.0% (alkalimetric); 99.0-101.0% (calc. on H2O free substance)
Density: 1.2580-1.2644 g/mL at 20 °C; ≥1.257 g/mL at 25 °C; 1.25 g/mL(lit.)
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.
