Table 1.
Proteins identified in the human cerebral microdialysate. The upper part contains proteins also found in CSF, the lower part lists additional proteins found in the microdialysate which have not been described in CNS. The first column gives the consecutive number of the identified protein, the second column the number of spots in the two-dimensional gels belonging to the individual proteins. The third and fourth column displays the protein annotation as in the SwissProt database at http://www.expasy.ch. The amino acid composition or structural information about the proteins can be retrieved via the accession number in the fifth column. This database also contains the CSF protein map. The sixth and seventh column shows pI and molecular weight. Strictly speaking, the immunoglobulin fractions do not represent a single protein, but a protein family, therefore pI and molecular weight cannot be given.
