Neurocan is a nervous tissue-unique, secretory proteoglycan that carries predominantly chondroitin sulfate side chains. Its expression gradually decreases with the nervous tissue development. In the immature brain, neurocan exists in a full-length form with a 240 kDa-core glycoprotein, whereas it exists totally in proteolytic fragments of the NH2-terminal half (neurocan-N) with a 130 kDa-core glycopeptide and the COOH-terminal half (neurocan-C) with a 150 kDa-core glycopeptide. Neurocan is implicated in the neural network formation, and is a susceptibility factor for bipolar disorder. This proteoglycan is upregulated in the lesion site of the central nervous system, and is a major component of the glial scar. In addition, neurocan-N, not neurocan-C, is detectable in the perineuronal nets of some neurons. This antibody recognizes effectively neurocan-N as well as the full-length neurocan.

Characterization of Neurocan peptides pAb and Neurocan peptides mAb (clone 1G2) with samples obtained from 10-day-old rat brain.
The PBS-soluble brain CSPG mixture of 10-day-old rats (lane 1) and the brain PBS-extract digested with chondroitinase ABC (lanes 2 and 3) were separated by SDS-PAGE. Neurocan peptides pAb recognized a very diffuse band with the same mobility as that recognized by Neurocan peptides mAb (clone 1G2). Monoclonal antibody (clone 1G2) recognized both 220 and 150 kDa core glycoproteins in the chondroitinase-digested sample. Polyclonal antibody recognized not only the 220 kDa core glycoprotein but also that with a molecular weight of 130 kDa in both. (Ref.3)
Distribution of neurocan in the adult rat cerebral cortex
A. The cell surfaces of some neurons were immunoreactive for anti-neurocan polyclonal antibody
B. Confocal image of the cerebral cortex of an adult rat double-labeled for neurocan-130 (red) and synaptophysin (green). Note neurocan-130 immunoreactivity surrounding
a neuronal cell body (n) and a proximal dendrite (large arrow). Neurocan-130 is absent in the axon terminals recognized by anti-synaptophysin (small arrows). (Ref.2)
