Background:
NPTX2 Antibody: Neuronal pentraxin (NPTX) 2 was initially identified as a member of the pentraxin family having high homology to NPTX1. Unlike NPTX1 however, NPTX2 is expressed in testes, pancreas, liver, heart, skeletal muscle as well as brain. NPTX2 possesses the lectin properties common to the pentraxin family, promotes neurite outgrowth, and is rapidly regulated by neuronal activity. NPTX1 and NPTX2 form heterocomplexes that contribute to both activity-independent and -dependent excitatory synaptogenesis. Recently, NPTX2 has been found to be highly upregulated in Parkinsonian substantia nigra and localizes to Lewy bodies and Lewy neurites in sporadic Parkinson's disease (PD), suggesting that it is involved in the pathway dysregulation that underlies PD. This NPTX2 antibody is predicted to be specific to NPTX2 and not recognize NPTX1.

VALIDATION:

Independent Antibody Validation in Cell lines (Figure 2) shows similar NPTX2 expression profile in human and mouse cell lines detected by two independent anti-NPTX2 antibodies that recognize different epitopes, 4573 against central domain and 64-234 against another central domain. NPTX2 proteins are detected only in HeLa and HepG2 cell lines by the two independent antibodies.
