Electrospray tandem mass spectrometry of aminochromes [PDF]

open access: bronzeRapid Communications in Mass Spectrometry, 2001
AbstractThe catecholamines adrenaline, noradrenaline, dopamine, dopa and isoprenaline were oxidized into their respective aminochromes: adrenochrome, noradrenochrome, dopaminochrome, dopachrome and isoprenochrome. Tandem mass spectrometry (MS/MS) fragmentation patterns were examined for the five aminochromes in order to establish a general structural ...

From sequence-defined macromolecules to macromolecular pin codes [PDF]

open access: yes, 2020
Dynamic sequence-defined oligomers carrying a chemically written pin code are obtained through a strategy combining multicomponent reactions with the thermoreversible addition of 1,2,4-triazoline-3,5-diones (TADs) to indole substrates.

Sucrose gradient chromatin enrichment for quantitative proteomics analysis in budding yeast

open access: yesSTAR Protocols, 2021
Summary: Here, we describe a fractionation protocol optimized to quantify changes in relative abundance of the chromatin-bound proteome (chromatome) by tandem mass tag multiplexing-based tandem mass spectrometry. It has been applied to yeast cells before

Seminolipid and its precursor/degradative product, galactosylalkylacylglycerol, in the testis of saposin A- and prosaposin-deficient mice

open access: yesJournal of Lipid Research, 2003
Sphingolipid activator proteins (saposins A, B, C, and D) are derived from a common precursor protein (prosaposin) and specifically activate in vivo degradation of glycolipids with short carbohydrate chains.
