Glycerol is used for storage of enzymes at low temperatures. A 50% (w/v) glycerol solution will not freeze at -20 degrees C. Glycerol is often used as a component in electrophoresis loading buffers because of its density (1.26g/ml). In addition, glycerol gradients can be used in the purification of bacteriophage or proteins. Cat.# H5433 is anhydrous glycerol with a purity of more than/=99.5%.|
Quality Tested: Each lot of glycerol is tested and certified to be free of DNase, RNase and protease activity.
