Ficoll PM70
High molecular weight sucrose-polymers formed by copolymerization of sucrose with epichlorohydrin. The molecules are highly branched and the high content of hydroxyl groups leads to very good solubility in aqueous media.
    
Displays minimal toxicity
    
Has favorable viscosity and osmotic properties

Reactivity and Stability
            
The reactivity and stability of Ficoll PM70 are determined by its hydroxyl groups and the glycosidic bonds in the sucrose residues. It is stable in alkaline and neutral solutions. At pH values lower than 3, it is rapidly hydrolyzed, especially at elevated temperatures. In neutral solutions, however, Ficoll PM 400 can be sterilized by autoclaving at 110°C for 30 min without degradation. Strong oxidizing and reducing agents should be avoided.

Solubility
            
It is delivered as a spray-dried powder and is therefore readily soluble in aqueous media when it is added slowly with concomitant stirring. Any lumps formed during this procedure will dissolve fairly quickly. Concentrations up to 50% (w/v) can easily be attained
