Preparation of Lactoferrin by Hydrophobic Interaction Chromatography from Milk Acid Whey

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...

Preparation and purification of Flavobacterium heparinum chondroitinases AC and B by hydrophobic interaction chromatography.

Flavobacterium heparinum is a soil bacterium that produces several mucopolysaccharidases such as heparinase, heparitinases I and II, and chondroitinases AC, B, C and ABC. The purpose of the present study was to optimize the preparation of F. heparinum chondroitinases, which are very useful tools for the identification and structural characterization of chondroitin and dermatan sulfates. We obse...
