Figure 7: Detection of carbohydrate moiety of HAP2 isoforms in normal (A) and NSCLC (B) serum samples using FITC-labeled lectins staining. The serum proteins from normal and NSCLC serum samples were separated on 2-DE and followed by transferred onto PVDF membrane. The 2-D gels were stained with four FITC-labeled lectins. Labels: 1, FITC-labeled WGA; 2, FITC-labeled ConA; 3, FITC-labeled PNA; 4, FITC-labeled UEA-I.
