Thus, the identification of novel targets is urgently needed to develop innovative agents to effectively control gastric cancer metastasis and progression. Previously, we reported a novel 12-mer peptide, GP-5 (IHKDKNAPSLVP), binding to gastric carcinoma (GC) cells specifically and sensitively, and it was screened by using a phage displayed peptide library and primarily analyzed. In this study, it was further identified via fluorescence microscopy, flow cytometry, tissue chip and other methods. Our results indicated that the peptide GP-5 presents a particularly high affinity and specificity to GC cells and tissues, whereas only background detection occurred with other control cancer cells, cancer tissues or normal tissues. Taken together, all results support that the peptide GP-5 is a potential candidate to be developed as a useful molecule fragment for the imaging detection and targeting therapy of GC. ? 2016 Elsevier Ltd.Gastric carcinoma; Molecular imaging diagnosis; Phage display peptide library; Targeting peptide; Targeting therapy[SDGs]SDG3antineoplastic agent; peptide; peptide gp 5; unclassified drug; peptide; protein binding; adult; aged; antigen specificity; Article; binding affinity; cancer cell; cancer control; cancer grading; cell proliferation; cells; clinical article; controlled study; drug binding; female; flow cytometry; fluorescence imaging; HEK293 cell line; human; human cell; human tissue; immunocytochemistry; immunohistochemistry; male; middle aged; molecularly targeted therapy; peptide library; priority journal; stomach cancer; tumor localization; cell death; fluorescence; fluorescent antibody technique; metabolism; stomach tumor; tissue microarray; tumor cell line; Adult; Aged; Cell Death; Cell Line, Tumor; Female; Flow Cytometry; Fluorescence; Fluorescent Antibody Technique; HEK293 Cells; Humans; Male; Middle Aged; Peptides; Protein Binding; Stomach Neoplasms; Tissue Array Analysisjournal article10.1016/j.mcp.2016.01.0072-s2.0-84956638031https://www.scopus.com/inward/record.uri?eid=2-s2.0-84956638031&doi=10.1016%2fj.mcp.2016.01.007&partnerID=40&md5=caea73630e078753a944938ce8071ece
