Calorimetry for studying the adsorption of proteins in hydrophobic interaction chromatography

Fractionation and recovery of whey proteins by hydrophobic interaction chromatography.

A method for the recovery and fractionation of whey proteins from a whey protein concentrate (80%, w/w) by hydrophobic interaction chromatography is proposed. Standard proteins and WPC 80 dissolved in phosphate buffer with ammonium sulfate 1 M were loaded in a HiPrep Octyl Sepharose FF column coupled to a fast protein liquid chromatography (FPLC) system and eluted by decreasing the ionic streng...

Hydrophobic Interaction Chromatography.

Most proteins and large polypeptides have hydrophobic regions at their surface. These hydrophobic "patches" are due to the presence of the side chains of hydrophobic or nonpolar amino acids such as phenylalanine, tryptophan, alanine, and methionine. These surface hydrophobic regions are interspersed between more hydrophilic or polar regions and the number, size, and distribution of them is a sp...

Modeling of adsorption in hydrophobic interaction chromatography systems using a preferential interaction quadratic isotherm.

A preferential interaction quadratic isotherm model for hydrophobic interaction chromatographic systems is presented in this paper. In this isotherm, the nonlinear effect of salt on the capacity factor is described using the preferential interaction model developed by Perkins et al. [J. Chromatogr. A, 766 (1997) 1]. This is then coupled with a quadratic nonlinear isotherm to describe nonlinear ...
