title: Preparation of reversed-phase microcolumns.
abstract: INTRODUCTIONOne versatile strategy for sample cleanup prior to MALDI-MS analysis uses microscale columns designed for direct sample elution onto the MALDI target plate. This protocol describes the fabrication of a reversed-phase microcolumn designed for this purpose. The microcolumns are prepared from GELoader tips. This protocol has been optimized for sample cleanup prior to MALDI-MS. However, with slight modifications, it works equally well with samples destined for ESI-MS.
