General description

A2B5 is a cell surface ganglioside epitope expressed in developing thymic epithelial cells, oligodendrocyte progenitors and neuroendocrine cells. The A2B5 antigen is present in type 2 astrocytes but absent in type 1 astrocytes, allowing for the differentiation of these different types of cells. A2B5 antibody has been used in flow cytometry and immunohistochemistry experiments to stain type II astrocytes, cells involved in gliogenesis and cells committed to the oligodendrocyte lineage.

Specificity

Recognizes an epitope common to silaogangliosides and sulfatides from the plasma membranes of neurons, and neuroendocrine and glial cells. Anti-A2B5 has been used to specifically stain:

Neurofibrillary tangles in the post-mortem brain tissue of patients with a confirmed diagnosis of Alzheimer′s disease (Majocha et al., 1989)
Neurons of chicken retina, brain, spinal cord, and dorsal root ganglia (Schnitzer & Schachner, 1982; Eisenbarth et al., 1979).
Rat striatal nerve terminals [synaptosomes (Wolf & Kapatos, 1989)].
Neuroblastoma cells in man (Oppedal et al., 1989; Coakham et al., 1985).
Rat insulinoma cells and pancreatic islets cells (Shimizu et al., 1983; Bartholomeusz et al., 1989).
Human and rat thymic epithelial cells (Haynes et al., 1988).
Cells involved in gliogenesis (Bottenstein et al., 1988; Suzumura & Slerberg, 1989).
Oligodendrocytes and astrocytes, type II (Dubois-Dalcq et al., 1990).

Immunogen

Embryonic chicken retinal cells

We have discovered that intracellular redox state appears to be a necessary and sufficient modulator of the balance between self-renewal and differentiation in dividing oligodendrocyte-type-2 astrocyte progenitor cells. The intracellular redox state of freshly isolated progenitors allows prospective isolation of
A2B5 lineages of human astrocytic tumors and their recurrence.
