Anti-Diasialoganglioside GD3 Antibody, clone R24

Evaluated by Flow Cytometry Analysis in SK-MEL-28 human skin melanoma cells.

Flow Cytometry Analysis: 0.2 µL of this antibody detected GD3 immunoreactivity on the surface of one million SK-MEL-28 human skin melanoma cells.

Affects Function: A representative lot induced cellular Lyn kinase activity and tyrosine phosphorylation of cellular proteins of primary rat cerebellar cultures in a time-dependent manner (Kasahara, K., et al. (1997). J. Biol. Chem. 272(47):29947-29953).

Affinity Binding Assay: A representative lot reacted with heat stable glycolipid on the surface of all SK-MEL melanoma and two of the five astrocytoma cells tested, whereas epithelial cell types, fibroblasts, and cells of hematopoietic origin were found to lack the surface antigen recognized by clone R24 (Dippold, W.G., et al. (1980). Proc. Natl. Acad. Sci. U.S.A. 77(10):6114-6118).

Flow Cytometry Analysis: A representative lot immunostained the surface of cultured primary rat cerebellar cells (Kasahara, K., et al. (1997). J. Biol. Chem. 272(47):29947-29953).

Immunocytochemistry Analysis: A representative lot immunostained NGF-induced nurite outgrowths of cultured DRG neurons from wild-type, but not GD3 synthase-knockout, mice (Ribeiro-Resende, V.T., et al. (2014). PLoS One. 9(10):e108919).

Immunohistochemistry Analysis: A representative lot detected GD3 immunoreactivity in unfixed frozen tissue samples of primary melanoma and metastatic malignant melanoma (Dippold, W.G., et al. (1985). Cancer Res. 45(8):3699-3705).

Immunoprecipitation Analysis: A representative lot co-immunoprecipitated Lyn from rat brain membrane extract. Clone R24 co-immunoprecipitated caveolin and the exogenously expressed Lyn, but not Src, from CHO cells expressing exogenous GD3 synthase (Kasahara, K., et al. (1997). J. Biol. Chem. 272(47):29947-29953).

Gangliosides are sialic acid-containing oligoglycosylceramides. They are classified based on the number of sialic acid residues per molecule. GM gangliosides contain one sialic acid residue, GD gangliosides contain two, GT contain three, and GQ contain four sialic acid residues. Sialyltransferase-catalyzed 2-3 sialylation of the galactose of the trisaccharide Gal 1-4Glc 1-1 Cer produces GM3, which can be further sialylated to produce GD3 with two sialic acid on the galactose. GD3 is found in melanocytes and other cells that originate in the neuroectoderm. It is expressed almost exclusively among gangliosides in the early stage of the brain development of mice and rats. It is also detected in the T cell malignant leukocytes, such as acute lymphoblastic leukemia cells, adult T cell leukemia cells, and in activated normal human T lymphocytes. GD3 is found in almost all melanomas and is considered as an important biomarker for malignant melanoma. GD3 positive cells show markedly increased cell growth and invasive characteristics. Suppression of GD3 expression with antisense GD3 synthase cDNA is shown to reduce tumor cell phenotypes such as growth, migration, metastasis, and angiogenesis in F11 cells. Intra-cytoplasmic domain of neogenin is reported to act as a driver to promote various cancer phenotypes. Ref.: Hamamura, K et al. (2005). Proc. Natl. Acad. Sci.
