Application:	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)
General description:	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.
Other Notes:	set contains 10 different dextran standards with 500 mg with M_p ~1,100 (Cat. No. 31416), ~4,400 (Cat. No. 31417), ~10,000 (Cat. No. 31418), ~20,000 (Cat. No. 31419), ~45,000 (Cat. No. 31420),~65,000 (Cat. No. 31421), ~125,000 (Cat. No. 31422), ~195,000 (Cat. No. 31423), ~275,000 (Cat. No. 31424), ~400,000 (Cat. No. 31425); The components can also be ordered separately under the product numbers indicated.
