Frequently Asked Questions
Live Chat and Frequently Asked Questions are available for this Product.
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.
Other Notes
Component of loading buffer in agarose gel electrophoresis of nucleic acids previously denatured with glyoxal1; Preparation of phage and plasmid DNA, for the storage of pure cultures2
Packaging
1 L in glass bottle
100, 250 mL in glass bottle
