詳細(xì)內(nèi)容

 Polysucroses (renamed from Ficoll™) are 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. Polysucroses behave as an ideal neutral sphere and displays excellent biocompatibility. Polysucrose does not contain any ionized groups, so it compatible under physiological conditions. Polysucrose is more sensitive to acid than dextran so that care must be taken when working at acid pH.

 

Properties of the polysucroses include:

Readily soluble in water and electrolyte solution

Clear and stable solutions

No charged groups - neutral polymer

Excellent biocompatibility

Excellent stability - can be autoclaved

From renewable resources and is readily degraded in ecological systems

 

Structure

Polysucrose is a polymer synthesised by cross-linking sucrose with epichlorohydrin. Polysucrose has a more spherical structure and is less flexible compared to dextran.

 

Storage and stability

Polysucrose is stable for more than 6 years when stored dry in well-sealed containers at ambient temperature.

 

Solubility

Polysucrose dissolves readily in water.

 

Application

Polysucrose behaves as an ideal neutral sphere and it displays excellent biocompatibility.

 

艾美捷Polysucrose(聚蔗糖)#P20、#P40、#P50等是由蔗糖與環(huán)氧氯丙烷共聚形成的。分子高度支化,羥基含量高,在水介質(zhì)中溶解度非常好。聚蔗糖是一種理想的中性球體,并顯示出優(yōu)異的生物相容性。聚蔗糖不含任何電離基團(tuán),因此在生理?xiàng)l件下相容。聚蔗糖比葡聚糖對(duì)酸更敏感,因此在酸性pH下工作時(shí)必須小心。
