Glycerol is used in gel formation of polyacrylamide gels for electrophoresis as well as sample preparation. Concentrations of 5% – 10% will increase sample density so that the sample will layer the bottom of the gel’s sample well. Glycerol is also used in aiding in the casting of gradient gels, used as a protein stabilizer and buffer component.
IBI provides glycerol in two sizes to fit the needs of your lab. 500ml and 1 liter.
