FITC-DEAE-polysucrose (C09-0892-309)

FITC-DEAE-Polysucrose is designed for special studies on membrane and transport properties in cells and tissues. FITC-DEAE-polysucroses are standard FITC-polysucroses carrying cationic (positively charged) diethylaminoethyl groups. All batches are checked for molecular weight, degree of substitution, loss on drying and free FITC. Aladdin produce FITC-DEAE-polysucrose with the molecular weight of either70 kDa or 400 kDa. FITC-DEAE-polysucrose is supplied as a yellow powder.Polysucrose are renamed from Ficoll™.StructurePolysucrose is a high molecular weight sucrose-polymers formed by copolymerisation of sucrose with epichlorohydrin. The molecules are highly branched, and the high content of hydroxyl groups leads to very good solubility in aqueous media. In FITC-DEAE-polysucrose, the content is approximately 5% which is equivalent to about one DEAE-group for every five glucose units. Fluorescein (FITC) groups are introduced by reaction with fluorescein isothiocyanate.Spectral dataExcitation maximum is 493 nm and emission maximum is 523 nm in pH 9.ApplicationFITC-DEAE-polysucrose is normally used for studying the permeability of polycationic polymers relative to neutral polymers in organs, tissues and cells. Polysucrose behaves as an ideal neutral sphere.
