DETAILS

Description (English)
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.
Biochem/physiol Actions
A sweet tastant for mammals. A glycerol taste receptor binding site specific for glucose has been proposed in drosophila.
Other Notes
Properties and use in density gradient centrifugation for rate-zonal separations 1,2; Data for the construction of isokinetic glycerol gradients for various rotor types3
Physical properties
0.6x sucrose
