Anti-PSA-NCAM antibodies, human, mouse, rat

Clone: 2-2B | Dilution: 1:50
The Anti-PSA-NCAM antibody recognizes an epitope on human, mouse, and rat polysialic acid (PSA) which, in vertebrates, is found linked to the extracellular domain of the neural cell adhesion molecule (NCAM, CD56). PSA-NCAM, the highly polysialated form of NCAM, is predominantly expressed in embryonic and neonatal neural tissue. In adult mammalian brain PSA-NCAM expression is restricted mainly to areas that retain neurogenic potential, such as the subventricular zone (SVZ) and the dentate gyrus of the hippocampus. PSA-NCAM is a marker for immature neuronal-committed progenitors that are permanently generated in the SVZ and migrate along a well-defined pathway, the rostral migratory stream, into the olfactory bulb where they differentiate into GABAergic and dopaminergic interneurons. Antibodies against PSA-NCAM have also been used to immunomagnetically isolate neuronal progenitors from postnatal mice and rat forebrain.
