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 carbohydrates on polysaccharide gel
Journal of Polymer Science: Polymer Symposia, 1980AbstractLiquid chromatographies of high and low‐molecular carbohydrates and polyethyleneglycols of different molecular masses were studied on porous microspherical cellulose. Dependence of the distribution coefficients of polymer molecules on molecular mass was determined.

Fluorinated gels for gel permeation chromatography
Die Makromolekulare Chemie, 1993AbstractThe aim of these investigations was the development of stationary phases for GPC compatible with fluorinated solvents. The properties of crosslinked copolymers of 4‐(2‐heptafluoropropoxy‐1, 2,2‐trifluoroethoxy)styrene (1) were investigated in dependence of the mode of synthesis. Divinylbenzene (DVB) was used as crosslinking agent.

Angewandte Chemie International Edition in English, 1970
AbstractGel chromatography can be regarded as a network‐limited partitioning of substances. The theory of this method and the preparation and properties of various gel systems are reviewed. Optimization of the method is illustrated for the separation of oligomers.

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.

The determination of myoglobin by gel chromatography
Analytical Biochemistry, 1978Abstract The method recently described for the determination of haemoglobin in ovine muscles (1) has now been modified for the measurement of myoglobin. Evidence is presented here for the validity of using it for myoglobin determination in muscles of the rat, pig, sheep, and ox.

Chromatography of glycogens on agarose gels
Journal of Chromatography A, 1973Abstract The chromatographic behavior of several glycogens on the agarose gels Sepharose 2B and Sepharose 4B has been investigated. These are shown to be convenient media for examination of the polydispersity and relative molecular weights of different glycogens.

Analytical Gel Chromatography of Proteins
1970Publisher Summary This chapter describes the fundamental aspects of gel chromatography as they comprise a set of analytical techniques that a protein chemist may use. The unifying principles that underlie these techniques have been a major focus of interest.

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.

Separation Science, 1971
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.
