Article: Phosphopeptide enrichment by IEF.
[show abstract] [hide abstract]
ABSTRACT: In our efforts to improve the identification of phosphopeptides by MS we have used peptide IEF on IPG strips. Phosphopeptides derived from trypsin digests of single proteins as well as complex cellular protein mixtures can be enriched by IEF and recovered in excellent yields at the acidic end of an IPG strip. IPG peptide fractionation in combination with MS/MS analysis has allowed us to identify phosphopeptides from tryptic digests of a cellular protein extract.Electrophoresis 12/2006; 27(22):4585-95. · 3.30 Impact Factor -
Article: The quest for brain disorder biomarkers.
[show abstract] [hide abstract]
ABSTRACT: The identification of disease markers in tissues and body fluids requires an extensive and thorough analysis of its protein constituents. In our efforts to identify biomarkers for affective and neurological disorders we are pursuing several different strategies. On one hand we are using animal models that represent defined phenotypes characteristic for the respective disorder in humans. In addition, we are analyzing human specimens from carefully phenotyped patient groups. Several fractions representing different protein classes from human cerebrospinal fluid obtained by lumbar puncture are used for this purpose. Our biomarker identification efforts range from classical proteomics approaches such as two dimensional gel electrophoresis and mass spectrometry to phage display screens with cerebrospinal fluid antibodies.The Journal of Medical Investigation 12/2005; 52 Suppl:231-5.
