Voltage-gated Na+ channels (NaV) are essential for the generation of action potentials and for cell excitability1. 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 NaV1.1-1.92,3. The NaV channels are classified into two groups according to their sensitivity to tetrodotoxin (TTX): TTX-sensitive and TTX-resistant channels4,5. Their expression is developmentally regulated and tissue specific.
Two TTX-resistant NaV channels are expressed in dorsal root ganglion (DRG) neurons, NaV1.8 and NaV1.9. The NaV1.8 channel (also called SCN10A, SNS and PN3) is mainly expressed in small-diameter DRG neurons4,6. TTX-resistant channels have been suggested to play an important role in nociceptive transmission.
Recently, the involvement of NaV1.8 in multiple sclerosis (MS) was suggested due to up-regulation of both mRNA and protein in Purkinje cells of MS patients and also in animal models6.
Species reactivity key:
Anti-NaV1.8 (SCN10A) Antibody (#ASC-016) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunoprecipitation, immunocytochemistry, and immunohistochemistry applications. It has been designed to recognize NaV1.8 from rat, human, and mouse samples.
Anti-NaV1.8 (SCN10A)-ATTO-594 Antibody (#ASC-016-AR) is directly labeled with an ATTO-594 fluorescent dye. ATTO dyes are characterized by strong absorption (high extinction coefficient), high fluorescence quantum yield, and high photo-stability. The ATTO-594 fluorescent label belongs to the class of Rhodamine dyes and can be used with fluorescent equipment typically optimized to detect Texas Red and Alexa-594. Anti-NaV1.8 (SCN10A)-ATTO-594 Antibody is specially suited to experiments requiring simultaneous labeling of different markers.
Antibodies for immuno-colocalization experiments
- Guinea pig Anti-NaV1.8 (SCN10A) Antibody (#AGP-029) is raised in guinea pig and can be used in immuno-colocalization studies in conjunction with any of our antibodies raised in rabbit. This antibody has been raised against the same epitope as #ASC-016.
Antibodies for live cell imaging experiments
- Anti-NaV1.8 (SCN10A) (extracellular) Antibody (#ASC-028). This antibody recognizes an extracellular epitope and can be used to detect NaV1.8 in live cells.
