Ion Exchange Applied to Sugar Juice Purification
Purification E. A. H A A G E N S E N 1 The process for recovering sugar from sugar beets has existed in its present form substantially unchanged since its inception over 100 years ago. There have been many improvements in technique and equipment but the essential methods have remained relatively the same. Now a new process of juice purification has been developed that promises to remove most of...

متن کاملIon-exchange chromatography purification of extracellular vesicles.
Despite numerous studies, isolating pure preparations of extracellular vesicles (EVs) has proven challenging. Here, we compared ion-exchange chromatography (IEC) to the widely used sucrose density gradient (SDG) centrifugation method for the purification of EVs. EVs in bulk were isolated from pooled normal human amniotic fluid (AF) by differential centrifugation followed by IEC or sucrose densi...
متن کاملpurification of human serum albumin by ion exchange chromatography
introduction : albumin, one of the most important plasma proteins, has a difficult process of synthesis and production. we compared two different methods for albumin purification: carboxymethyl cellulose (cm cellulose) resin exchange and diethylaminoethyl cellulose (deae cellulose) resin exchange in order to determine which resin could be more beneficial. materials and methods : two ion exchang...
متن کاملLaboratory Exercises Assessment of the Purification of a Protein by Ion Exchange and Gel Permeation Chromatography
A 3-week group laboratory project experiment that involves the partial purification of myoglobin (Mb) from bovine hamburger is described. The experiment compares alternate purification methods (gel filtration and ion exchange chromatography) as to both overall yield and enhancement in relative purity. The purity and molecular weight of purified Mb is established by SDS-PAGE. Group reports are d...
