Anion exchange chromatography of acids of the citric acid cycle.
The demonstration of the accumulation of citrate in vivo in the presence of fluoroacetate and the specific modification of this effect produced in various organs by the injection of malonate (14) have increased the desirability of isolation and quantitative determination of the acids of the Krebs cycle and related substances. Further, proposed studies involving the use of radioactive tracers re...
متن کاملAnalysis of Sialic Acids Using High-Performance Anion-Exchange Chromatography
INTRODUCTION Sialic acids comprise a large family of Nand O-substituted neuraminic acids. The amino group of neuraminic acid is linked to either an N-acetyl or N-glycolyl group, which yields N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc), respectively. The hydroxyls of both sialic acids are often modified. The biosynthesis, function, and occurrence of sialic acids have ...
متن کاملAnion-Exchange Chromatography of Phosphopeptides: Weak Anion Exchange versus Strong Anion Exchange and Anion-Exchange Chromatography versus Electrostatic Repulsion–Hydrophilic Interaction Chromatography
Most phosphoproteomics experiments rely on prefractionation of tryptic digests before online liquid chromatography-mass spectrometry. This study compares the potential and limitations of electrostatic repulsion-hydrophilic interaction chromatography (ERLIC) and anion-exchange chromatography (AEX). At a pH higher than 5, phosphopeptides have two negative charges per residue and are well-retained...
متن کاملPurification of DNA by anion-exchange chromatography.
Column chromatography has evolved to provide a rapid and effective alternative to more laborious methods for preparing high-quality DNA, such as CsCl-gradient centrifugation. This unit describes the use of a column made of a unique anion-exchange resin that selectively binds nucleic acids, allowing rapid separation of DNA from contaminating RNA, proteins, carbohydrates, and metabolites. The pro...
متن کاملRegeneration Studies of Anion-Exchange Chromatography Resins
LEVEL: INTERMEDIATE C hromatography columns can become contaminated by a variety of protein and nonprotein species during a purification campaign. Consequences of column contamination include an increase in backpressure, loss of signal resolution, altered product yield, and medium discoloration. Common chromatographic contaminants include • residual proteins • nucleic acids • lipids • endotoxin...
