Figure 1: 2-DE analysis images of healthy control and lung cancer patient urine samples. Atotal of 200 µg of urine samples from healthy donors and lung cancer patients were applied toa pI 4-7 IPG strip for the first dimension and separated on 15% SDS-PAGE gel for thesecond dimension in the 2-DE. The gels were strained by using Sypro Ruby. (A) Pooled urinesamples of healthy controls and lung cancer patients. (B) Urine samples of healthy donor andpatients with different subtypes of lung cancer, N: Healthy control. L: Lung cancer patient(L1: Adenocarcinoma, L2: Small cell lung cancer, L3: Squamous cell carcioma, L4: Othertypes of carcinoma). The black circles indicate the position of GM2AP. They are overexpressed in each subtype of lung cancer patients when compared with that of healthydonors.
