Other Notes
Isopycnic centrifugation in a discontinuous sucrose density gradient e.g. in the isolation of mRNA from membrane-bound polysomes1
Application
Sucrose is a widely used nutitional disaccharide of glucose and fructose. Sucrose is used in molecular biology for the preparation of density gradients.
