N-2 Supplement (100X) liquid

For the growth and expression of post-mitotic neurons and tumor cells of neuronal phenotype.

N-2 supplement is a chemically defined, 100X concentrate of Bottenstein's N-2 formulation (1). This supplement is recommended for the growth and expression of neuroblastomas and for the survival and expression of post-mitotic neurons in primary cultures from both the peripheral nervous system (PNS) and the central nervous system (CNS). It can be used as a substitute for the N-1 Bottenstein formulation. N-2 medium appears to be selective for neuronal cell lines and does not support the growth of nonneuronal cell lines.
