Human milk (HM) is unique compared with the milk of other species in that nonprotein nitrogen (NPN) constitutes 20-25% of the total N. The NPN fraction consists of a diverse group of compounds with molecular masses less than 10,000 Da (in the picogram to

Abstract The technique of gel filtration chromatography is described, with a guide to relevant literature on methods, theory, and applications, especially the use of GFC in analysis of molecular interactions, both macromolecular and small molecule-macromolecule aggregation.

Immobilized metal ion affinity adsorption (IMA adsorption) is a collective term that is proposed to include all kinds of adsorptions whereby metal atoms or ions immobilized on a polymer cause or dominate the interaction at the sorption sites.

A generally applicable, rapid, and sensitive method for profiling and sequencing of glycoprotein-associated N-linked oligosaccharides from protein gels was developed. The method employed sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE)

Abstract Gel permeation chromatography is the most valuable single technique in the molecular weight characterisation of polymers. The power of this technique lies in its ability to give information on the whole molecular weight distribution. In Britain, the Polymer Supply and Characterisation Centre provides a GPC service for research workers in the

Gel Permeation Chromatography of Heparins
Thrombosis and Haemostasis, 1980SummaryGel permeation chromatography of heparins using water as solvent has recently been used to obtain fractions for biological investigation. We find that heparin fractions obtained in this way are not, necessarily, differentiated simply on a molecular size basis as has been alleged.
