Miniaturized solid-phase extraction and sample preparation for MALDI MS using a microfabricated integrated selective enrichment target

Ekström, Simon LU ; Wallman, Lars LU ; Hok, D ; Marko-Varga, György LU and Laurell, Thomas LU (2006) In Journal of Proteome Research 5(5). p.1071-1081
Abstract
A microfabricated proteomic sample preparation and sample presentation device, Integrated Selective Enrichment Target, (ISET), comprising an array of 96 perforated nanovials is described. Each perforated nanovial can be filled with solid-phase extraction media for purification and concentration of peptides prior to matrix-assisted laser desorption/ionization mass spectrometry (MALDI IVIS). The validity of the ISET sample preparation is shown by analysis of low nM-pM standard samples, as well as biological samples. The ISET solid-phase extraction sample preparation was compared to ZipTip and MassPREP PROtarget sample preparation, demonstrating a superior performance with respect to number of detected peptides and signal intensity of...
