General description

Ion-pairing reagents, when used as mobile phase additives, promote the analysis of ionic and highly polar substances on reversed phase HPLC columns. The purity of mobile phase additives is of highest significance for their effective application. Sigma-Aldrich makes available a variety of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) separations. All mobile phase additives are tested thoroughly with special consideration on the demands of modern reversed phase HPLC:

Potassium homeostasis is crucial for living cells. In the yeast Saccharomyces cerevisiae, the uptake of potassium is driven by the electrochemical gradient generated by the Pma1 H(+)-ATPase, and this process represents a major consumer of the gradient. We considered that

The aim of this study was to explore the synergies of laccase, a ligninolytic enzyme, with cellulose and hemicellulase amendments on ensiled corn stover. Molecular signals of lignin decomposition were observed by tetramethylammonium hydroxide thermochemolysis and gas chromatography-mass spectroscopy (TMAH-GC-MS)
