Peptide mapping of proteins in cerebrospinal fluid utilizing a rapid preparative two-dimensional electrophoretic procedure and matrix-assisted laser desorption/ionization mass spectrometry
A quick two-step procedure involving liquid phase isoelectric focusing in the Rotofor cell in combination with electroelution in the Mini whole cell gel eluter has been used for purification of proteins from human cerebrospinal fluid (CSF). Fractions, each highly enriched in a single protein band and virtually free of other proteins, were selected for characterization by matrix-assisted laser deso
