Figure 2: Protein identification and image analysis of HAP2 in normal and NSCLC serum samples. (A) 2-DE images of HAP2 regions in both normal and NSCLC serum samples and 3-D viewing. Labels: N, normal serum with the different isoforms of HAP2 (N1, N2); L, NSCLC serum with the different isoforms of HAP2 (L1, L2). (B) Protein sequence of identified HAP2 (Swiss-Prot accession no. P00738) and NH2-terminal amino acid sequence (underline).
