Descripción general

Dextran is an exopolysaccharide synthesized by lactic acid bacteria from sucrose. It consists of repeating units of D-glucose with the monomers joined to each other through α-1,6 linkages. In addition, the linear D-glucose chains show branching at frequent intervals, linked by α-1,4, α-1,3, or α-1,2 linkages.

Aplicación

The analytical standards can also be used as follows:
  • High-performance size exclusion chromatography (HPSEC) based determination of the molecular weight of a dextran synthesized by Leuconostoc citreum B-2, isolated from a fermentation product of pineapple
  • Determination of molecular weight of polysaccharides obtained from four Auricularia species by high-performance liquid chromatography using a water-soluble gel column
  • Identification of molecular weight of a water-soluble polysaccharide isolated by anion exchange chromatography from the dried leaves of C. paliurus by gel permeation chromatography (GPC)
  • Gel permeation chromatography (GPC) based molecular weight measurement of a dextran produced by two strains of Leuconostoc mesenteroides
  • Estimation of molecular weight of a water-soluble polysaccharide obtained from thinned-young apple by high-performance size exclusion chromatography (HPSEC)

Componentes

Set enthält 10 verschiedene Dextran Standards à 500 mg mit Mp ~1100 (Fluka® 31416), ~4400 (Fluka 31417), ~10000 (Fluka 31418), ~20000 (Fluka 31419), ~45000 (Fluka 31420), ~65000 (Fluka 31421), ~125000 (Fluka 31422), ~195000 (Fluka 31423), ~275000 (Fluka 31424), ~400000 (Fluka 31425); Die Komponenten können auch einzeln unter den angeführten Fluka Produktnummern bestellt werden.
