Figure 1

Differentially expressed proteins in tissue interstitial fluid of non-small cell lung cancer biopsies. The two-dimensional electrophoresis gel is representative of all the tissue interstitial fluid samples, since it has been obtained by pooling tissue interstitial fluid of all patients. Spot number reflects the number listed for the specific protein in Table 1. Molecular weight (kDa) and isoelectric values (pI) are shown on the image. (A) Non-tumor adjacent tissue; (B) tumor.
