In our previous study, and using flow cytometry, we demonstrated that both SM3GRNLY and iSM3GRNLY recognized MUC1-Tn expression on the surface of living tumor cells previously reported to be positive for the expression of this antigen, including the pancreatic adenocarcinomas Panc-1 and CAPAN-2, the multiple myeloma NCI-H929 an the acute lymphocytic leukemia Jurkat, with low binding to lung adenocarcinoma A549 [22]. Here, MUC1 is linked to neoplasm.
