Using a panel of 37 lectins immobilized on a lectin microarray, the normalized fluorescence intensity measured with T/Tn-specific lectins (jacalin, MPL from Maclura pomifera, DBA from Dolichos biflorus, ACA from Amaranthus caudatus and VVA from Vicia villosa) measured for Cy3-labeled gastric cancer cell glycoproteins was stronger compared to the fluorescent intensity measured for Cy3-labeled gastric ulcer cell glycoproteins [123]. This evidence concerns the gene MPL and gastric ulcer.
