High-performance anion-exchange chromatography of homogeneous D-gluco-oligosaccharides and -polysaccharides (polymerization degree >=50) with pulsed amperometric detection


, : High-performance anion-exchange chromatography of homogeneous D-gluco-oligosaccharides and -polysaccharides (polymerization degree >=50) with pulsed amperometric detection. Journal of Chromatography 464(2): 365-373

The method successfully separated homogeneous ((1->2)-, (1->3)-, (1->4)- or (1->6)-), alpha - or beta -linked D-glucosaccharides with DP up to and even somewhat above 50. With isocratic elution by 150 mM NaOH + 100 mM Na acetate, there was a linear relation between log k' (a dimensionless expression of retention time) and DP. Effective separation was achieved by gradient elution with 150 mM NaOH + a gradually increasing concentration of Na acetate (up to 500 mM).

Toxic aluminum enters the root cells rapidly, therefore internal detoxification is required. However, the molecular mechanisms underlying this process are poorly understood. Here we functionally characterized a rice gene, Os03g0755100 (OsALS1), th...
