Regulatory Status Legend
Gangliosides are sialic-acid bearing glycolipids that are expressed on the surface of all mammalian cells, and are likely involved in mediating cell-substratum interactions. They are important target antigens for antibody dependent cellular cytotoxicity (ADCC) of human melanoma and neuroblastoma cells. Human melanoma cells produce gangliosides, designated as GD2 and GD3 which are deposited in the subtratum-attached material, and may play a significant role in the melanoma metastatic phenotype. Clone 14.G2a specifically reacts with human and mouse GD2 ganglioside. LAN-1 human neuroblastoma cells were used as immunogen. Clone 14.G2a is an isotype switch variant selected from the parental IgG3-producing hybridoma 14.18 and has identical reactivity as the parental antibody. Clone 14.G2a is routinely tested by flow cytometry using M21 human melanoma cells.
Alexa Fluor® 647 conjugates are highly photostable and remain fluorescent over a broad pH range. The excitation and emission maxima are nearly identical to those of APC. However, APC tends to be brighter while Alexa Fluor® 647 is more optimal for intracellular applications. This fluorochrome exhibits uncommon photostability, making it an ideal choice for use in fluorescence microscopy. Due to nearly identical excitation and emission properties but different spillover characteristics, APC and Alexa Fluor® 647 cannot be used simultaneously.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
The antibody was conjugated to Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
- Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
