    Reactivity and stability
    The reactivity and stability of Ficoll&#8482; PM400 are determined by its hydroxyl groups and the glycosidic bonds in the sucrose residues. It is stable in alkaline and neutral solutions. At pH &#118alues lower than 3, it is rapidly hydrolyzed, especially at elevated temperatures. In neutral solutions, however, Ficoll&#8482; PM 400 can be sterilized by autoclaving at 110°C for 30 min without degradation. Strong oxidizing and reducing agents should be avoided.
