Metildi et al. established that FGS for pancreatic cancer reduced tumor burden and improved overall survival in mouse models using fluorescently labeled human pancreatic cancer cell lines using an AlexaFluor 488 Dye (ThermoFisher Scientific, Waltham, MA, USA) conjugated to a chimeric anti-CEA antibody. This evidence concerns the gene CEACAM5 and neoplasm.
