usage and synthesis

chemical properties

clear, colorless, viscous liquid. combustible but may require some effort to ignite. residual sodium hydroxide (lye) causes crude material to be corrosive to metals and/or tissue.

usage

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.
