Ion-exchange chromatography purification of extracellular vesicles

open access: yesBioTechniques, 2017
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

Identification of novel components of Trypanosoma brucei editosomes [PDF]

open access: yes, 2003
The editosome is a multiprotein complex that catalyzes the insertion and deletion of uridylates that occurs during RNA editing in trypanosomatids. We report the identification of nine novel editosome proteins in Trypanosoma brucei.

Water, electricity and ion exchange; how Hamish Small sustained the evolution of ion chromatography

open access: yesHeliyon, 2021
Since the development of synthetic ion exchange resins in 1935, the electrochemical properties of these unique materials have intrigued researchers. In 1951, Hamish Small was introduced to synthetic ion exchange resin when he studied the electromigration

Purification and Characterization of a Chloroplast Outer-Envelope-Bound, ATP-Dependent Protein Kinase [PDF]

open access: yes, 1988
An ATP-dependent protein kinase was partially purified from isolated outer envelope membranes of pea (Pisum sativum L., Progress No. 9) chloroplasts. The purified kinase had a molecular weight of 70 kilodaltons, as determined by sodium dodecyl sulfate ...

Separation of Natural Collagen Crosslinks Using Buffer and Ion-pairing Agent Free Solvents on Silica Hydride Column for Mass Spectrometry Detection

open access: yesBio-Protocol, 2019
In this protocol we describe the separation of collagen crosslinks in biological tissues and samples including skin, tendon, cartilage, bone and urine. The existing methods use either cation exchange chromatography followed by post-column derivatization ...
