Biochemistry, 1976
In the course of a routine investigation of the complex between the erythrocyte membrane protein spectrin and sodium dodecyl sulfate, we observed a large discrepancy between the true Stokes radius (178 A, measured by hydrodynamic methods) and the ...

Journal of Chromatography A, 1976
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

Analytical Chemistry, 1993
A tetraphenylporphyrin-based stationary phase for high-performance liquid chromatography is prepared by attaching a p-carboxyphenyl derivative of the porphyrin to aminopropyl silica gel through an amide bond. This stationary-phase support is used for the

A sol−gel chemistry-based novel approach to column technology for high-resolution capillary gas chromatography is described that effectively combines surface treatment, deactivation, coating, and stationary phase immobilization into a single step. In the

GEL CHROMATOGRAPHY OF HUMIC ACID
, 1971Summary Gel-solute interactions have been reported in the application of gel chromatography to humic acid. The origins and nature of these interactions are discussed with particular reference to the behaviour of ‘Sephadex’ with compounds which are ...

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 ...
