Abstract:
1. A method of diagnosing gastric cancer by using human neutrophil peptide (HNP) 1-3, comprising the steps of: (a) obtaining samples consisting of a gastric tissue from a patient and a normal gastric tissue; (b) determining the amount of protein biomarkers HNP1, HNP2 and/or HNP3 in the samples using MALDI-TOF mass spectrometry; wherein said three protein biomarkers have molecular weights of 3370(HNP1), 3442(HNP2) and 3486(HNP3); and (c) diagnosing a gastric cancer at an early stage if the amount of each biomarker in the patient sample is higher than the amount in normal sample.
