Figure 2. Two-dimensional reference map of xenotransplanted pediatric medulloblastoma tumors. Extracted proteins from the tumors were separated on 3-10 non-linear IPG strips, followed by 12% SDS-polyacrylamide gel electrophoresis, as descried in Materials and Methods. 2-DE gels were stained with Coomassie blue and protein spots were excised and further analyzed by MALDI-TOF MS. The proteins that were found present in all samples analyzed are designated with their accession numbers.
