质谱仪

When total protein was assayed by 2-D PAGE andstained with sliver, about 2000 protein spots with a pI of pH 3-10 and Mrof 12-120 kDa could be detected. All these protein spots were excised foridentification, among which 213 spots corresponding to 192 differentproteins were identified undoubtful by searching the mass spectra againstthe SwissProt/TrEMBL database.
