PRODUCT DESCRIPTION
Glycerol
Application Notes
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 gels sample well. Glycerol is also used to aid in casting gradient gels and as a protein stabilizer and storage buffer component. It is used in the concentration and storage of enzymes and also prevents back-diffusion of protein samples into the buffer.
