Identifi cation of Central Nervous System Proteins in Human Blood Serum and Plasma

Mass-spectrometric identification of proteins in human blood plasma and serum was performed by comparing mass-spectra of fragmented peptides using Swiss-Prot and UniProtKB databases of amino acid sequences. After choosing the appropriate identification conditions we found that combination of spectrum search parameters are optimal for identification of CNS proteins. In the studied plasma and serum samples, 9 proteins involved into pathological processes in the nervous tissue were identified; 7 of them were identified in both plasma and serum.
