Reacts with a surface antigen on neurons in the retina, brain, spinal cord and dorsal root ganglia, and with all tested human neuroblastoma cell lines. Does not seem to bind with any leukemic cell lines or with bone marrow cells from patients with leukemia, nor with cells from normal bone marrow. Cytotoxic to neurons in the presence of guinea-pig complement. Protein A binding is positive. Binds with GQ ganglioside on the plasma membrane of neurons of animals of all species tested to date (Eisenbarth, et al., 1979).


Embryonic chicken retinal cells


Detect A2B5 using this Anti-A2B5 Antibody, clone A2B5-105 validated for use in FC, IC, IF, IH.

Indirect immunofluorescence (1:100 - 1:500) in the detection of neurons in tissue culture.

Using double immunofluorescence the GQ ganglioside has a similar distribution on neurons to the D2 protein, to the tetanus toxin receptor and to neurofilaments (Walsh, 1980).

May also be used in the depletion of neurons for a mixed population or their purification by affinity chromatography.

May also be useful for detecting the metastatic spread of neuroblastoma cells into bone marrow.

Flow cytometry: live cells {Maric, D. et al. (2000) Cerebral Cortex 10:729-747}.

Immunohistochemistry: Frozen, fixed tissues (Levison & McCarthy, 1989)

Complement-mediated cytotoxicity (Eisenbarth et al., 1979)
