Racotumomab (Anti-Human NGcGM3 Recombinant Antibody) is a mouse γ-type anti-recombinant antibody. It can specifically induce an antibody response against Neu-glycolyl GM3 ganglioside (NeuGcGM3), which is overexpressed in a variety of solid tumors. Racotumomab reacts with gangliosides containing NU-Glycolyl (NeuGc), thioglycosides, and other antigens expressed in tumors. Racotumomab has anti-cancer activity and can be used in the study of lung cancer.
