The ion exchange column

Objectives of the dissertation: Successfully synthesis polymers containing suitable funtional groups to seperate the light rare earth element (La, Nd, Pr, and Ce); evaluted the efficiency of polymers on seperating light rare earth element; evaluated the ability of polymers on separating each of the rare earth metal ions on the ion exchange column.

Glycosphingolipids (GSLs) were purified from adults and plerocercoids of the tapeworm Diphyllobothrium hottai, and their chemical structures were determined. Total lipid fractions prepared from chloroform/methanol extracts of whole tissues were fractionated successively on ion-exchange chromatography, silicic acid column chromatography, and preparative TLC. The purified GSLs were characterized by methylation analysis, TLC-immunostaining, liquid secondary ion MS, MALDI-TOF MS, and 1H-NMR.

Protein oligomeric complexes have emerged as a major target of current research because of their key role in aggregation processes in living systems andin vitro. Hydrophobic and charged surfaces may favour the self-assembly process by recruiting proteins and modifying their interactions. We found that equine lysozyme assembles into multimeric complexes with oleic acid (ELOA) at the solid–liquid interface within an ion-exchange chromatography column preconditioned with oleic acid.
