- Expression of NaV1.9 in rat embryo DRGImmunohistochemical staining of formalin frozen rat embryo dorsal root ganglion (DRG) sections with Anti-SCN11A (NaV1.9) Antibody (#ASC-017). A. Cells within the DRG were stained (see solid line frame enlarged in B) as well as fibers and the area of entry of dorsal root into the spinal cord (see dashed line frame enlarged in C). DAPI is used as the counterstain.

Voltage-gated Na+ channels (NaV) are essential for the generation of action potentials and for cell excitability.1 NaV channels are activated in response to depolarization and selectively allow flow of Na+ ions. To date, nine NaV α subunits have been cloned and named NaV1.1-1.9.2-3 Expression of the α subunit is developmentally and tissue specific.
The NaV channels are classified into two groups according to their sensitivity to tetrodotoxin (TTX): TTX-sensitive and TTX-resistant channels.4-5 TTX-resistant channels have been suggested to play an important role in nociceptive transmission. Two TTX-resistant NaV channels are expressed in dorsal root ganglion (DRG) neurons, NaV1.8 and NaV1.9. The NaV1.9 channel (also called SCN11A, NAN or SNS2) is preferentially expressed in small-diameter DRG neurons.4-5
Recently, it was shown that BDNF activates NaV1.9 channels in the hippocampus suggesting that its expression is not restricted to DRG alone.6
Species reactivity key:
Anti-SCN11A (NaV1.9) Antibody (#ASC-017) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunocytochemistry, and immunohistochemistry applications. It has been designed to recognize NaV1.9 channel from rat, human, and mouse samples.
