Název v původním jazyce
Complementary matrix-assisted laser desorption/ionization and inductively coupled plasma mass spectrometry detection of single separation record
Popis výsledku v původním jazyce
The analyses of native metal-protein and metal-metabolite complexes by hyphenated techniques that combine separation with a specific detection is of growing importance. Using a liquid junction, capillary electrophoresis (CE) was coupled in the off-line mode to both matrix-assisted laser desorption/ionization mass spectrometry (MALDI) and substrate-assisted laser desorption inductively-coupled plasma (SALD ICP) mass spectrometry (MS). Here we present a new approach for an off-line multidetection platformfor metalloprotein/metallopeptide analysis of fractions collected from a single CE run. CE fractions are collected on a special target and analyzed consecutively with MALDI MS and SALD ICP MS. The concept is demonstrated on the CE-MALDI/SALD ICP MS analysis of rabbit liver metallothionein (MT) isoforms: The mixture of MT isoforms was separated in uncoated fused silica capillary (70 cm, 75um) using 20 mM ammonium bicarbonate buffer, pH 7.4 as background electrolyte.
