Principles of gel chromatography
Journal of Chromatography A, 1970Abstract The principles of gel chromatography have been examined with regard to general chromatographic theory. It is shown that the elution volume for a solute is solely determined by the partition of a solute between the mobile and stationary phases and that various forms of diffusion only contribute to the width of the peak eluted.

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.

Endeavour, 1984
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.

Abstract An automated gel permeation chromatograph-low-angle laser light-scattering system capable of measuring the molecular-weight distribution of soluble polymers without the necessity of calibration is described. The automation system eliminates most of the tediousness associated with molecular-weight distribution measurement.

Bacteriophage purification by gel chromatography
Analytical Biochemistry, 1981Abstract We have developed an inexpensive procedure for bacteriophage purification suitable for small- and medium-scale preparations (up to one liter of lysate). The method consists of precipitation with polyethylene glycol 6000 and gel chromatography on a Bio-Gel A-5m column. The purity of the phage preparation is comparable to that obtained by CsCl

Gel chromatography of sunflower proteins
Journal of Agricultural and Food Chemistry, 1973The salt-extractable proteins in sunflower flour were characterized by gel chromatography, disk electrophoresis, and amino acid composition. The proteins from Commander, Majak, and Valley sunflower and a soybean control were 69-70% dispersible in 2.5% neutral salt solution.

Gel Permeation Chromatography of Polyelectrolytes
Journal of Liquid Chromatography, 1981Abstract The mechanisms are discussed which control the GPC elution of ionic solutes, both the polyelectrolytes and the low molecular salts. The processes involved are quite general and valid in organic and in aqueous solvents. The conclusion is that gel permeation chromatography is a powerfull method to characterize poly-electrolytes; and it is shown ...

Determination of the structure of agarose gels by gel chromatography
Biochimica et Biophysica Acta (BBA) - General Subjects, 1967Abstract Well-characterized fractions of the synthetic polysaccharide Ficoll have been chromatographed on columns of pearl-condensed agarose gels of concentrations between 2 and 8%. The results agree with the theory that the Ficoll is sterically excluded from the gel, which is made up of a random three-dimensional network of long fibers.
