Flow cytometric analysis of HeLa (Human cervix adenocarcinoma epithelial cell, Left) / U-2 OS (Human bone osteosarcoma epithelial cell, Right) labelling Ganglioside GD2 antibody at 1/200 dilution (1 μg) / (Red) compared with a Rabbit monoclonal IgG (Black) isotype control and an unlabelled control (cells without incubation with primary antibody and secondary antibody) (Blue). Goat Anti - Rabbit IgG Alexa Fluor® 488 was used as the secondary antibody. Negative control: HeLa

Background
Ganglioside GD2 is a tumor-associated antigen that is highly expressed in various neuroectodermal tumors, including neuroblastomas, melanomas, and retinoblastomas. It plays a role in tumor development by enhancing cell proliferation, motility, migration, adhesion, and invasion. GD2 is also considered a promising target for cancer immunotherapy, with anti-GD2 antibodies not only binding to tumor cells but also inducing rapid cell death in GD2-positive tumor cells, suggesting a new role for GD2 as a receptor that actively transduces death signals in malignant cells. In normal tissues, GD2 expression is mostly restricted to neurons, skin melanocytes, and peripheral nerves, and it is either not expressed or expressed at very low levels. The high expression of GD2 in tumor cells compared to its low expression in normal cells makes it an attractive target for monoclonal antibody therapies, which have been used in clinical trials with some success.

Immunohistochemistry
IHC shows positive staining in paraffin-embedded human breast cancer. Anti-Ganglioside GD2 antibody was used at 1/250 dilution, followed by a HRP Polymer for Mouse & Rabbit IgG (ready to use). Counterstained with hematoxylin. Heat mediated antigen retrieval with Tris/EDTA buffer pH9.0 was performed before commencing with IHC staining protocol.
