Sodium Channel, Voltage-Gated, Type IX, alpha (SCN9A) (C-Term) antibody

Antigen: Sodium Channel, Voltage-Gated, Type IX, alpha (SCN9A)

Epitope: C-Term

Clonality: Polyclonal

Host: Rabbit

Application: Immunohistochemistry (IHC), Western Blotting (WB)

Catalog no.: ABIN350859

Additional Information

Alternative name: Sodium channel protein type 9 subunitalpha (SCN9A, Nav1.7) (c-terminal region)

Swiss-Prot: Q15858

Immunogen: A synthetic peptide from the c-terminal region of human Sodium channel protein type 9 subunit alpha (SCN9A, Nav1.7) conjugated to an immunogenic carrier protein was used as the immunogen.

Format: Lyophilized

Description: FUNCTION: Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na+ ions may pass in accordance with their electrochemical gradient. It is a tetrodotoxin-sensitive Na+ channel isoform. Plays a role in pain mechanisms, especially in the development of inflammatory pain. Tissue specificity: Expressed strongly in dorsal root ganglion, with only minor levels elsewhere in the body, smooth muscle cells, MTC cell line and C-cell carcinoma. Isoform 1 is expressed preferentially in the central and peripheral nervous system while isoform 2 is expressed preferentially in the dorsal root ganglion. SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. Note: In neurite terminals Also known as: Sodium channel protein type IX subunit alpha, Voltage-gated sodium channel subunit alpha Nav1.7, Neuroendocrine sodium channel, Peripheral sodium channel 1, SCN9A, NENA, PN1.

Specificity: Appears to be specific for SCN9A.

Application Details

Application Notes: IHC, WB. A dilution of 1 : 300 to 1 : 2000 is recommended. The optimal dilution should be determined by the end user. Not yet tested in other applications.

Purity: whole serum

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Restrictions: For Research Use only
