Anti-ganglioside GD2 (anti-GD2) is very useful in the identification of disialoganglioside GD2 and in immunotargeting cells expressing disialoganglioside GD2. Several gangliosides have been found to have elevated expressions in tumor cells. Many therapeutic treatments of tumor cells are being investigated using antibodies to target cells that express these elevated levels of gangliosides. Disialoganglioside GD2 has been identified as a tumor-associated antigen and therapeutic approaches using anti-GD2 are being investigated and show great potential.1 Although many challenges must still be overcome in using this therapeutic approach progress is steadily going forward.2
