- Expression of NaV1.5 in rat cardiac muscleImmunohistochemical staining of NaV1.5 in rat myocardium paraffin-embedded section using Anti-NaV1.5 (SCN5A) (1978-2016) Antibody (#ASC-013), (1:100). Staining is specific for cardiomyocytes while smooth muscles cells in the artery walls are negative (red arrows). Hematoxilin is used as the counterstain.

Voltage-gated Na+ channels (NaV) are responsible for myocardial conduction and maintenance of the cardiac rhythm and are essential for the generation of action potentials and cell excitability.1
Dysfunction or disregulation of cardiac sodium channels can cause several disorders, including cardiac arrhythmias.
The majority of Na+ channels in the mammalian heart are Tetrodotoxin (TTX) insensitive NaV1.5.2
The putative structure of NaV1.5 consists of four homologous domain (I-IV), each containing six transmembrane segments (S1-S6). Mutations in the C-terminus of NaV1.5 were described in connection to Long QT syndrome and Brugada syndrome.1-2 Recent data have demonstrated selective expression of NaV1.5 in the mouse central nervous system and implicated a role for NaV1.5 in the physiology of the central nervous system.1

Alomone Labs is pleased to offer a highly specific antibody directed against an epitope of human NaV1.5 channel. Anti-NaV1.5 (SCN5A) (1978-2016) Antibody (#ASC-013) can be used in western blot, indirect flow cytometry, immunohistochemistry, and immunocytochemistry applications. It has been designed to recognize NaV1.5 sodium channel from rat, human, and mouse samples.
- Multiplex staining of neuronal NaV channels and Ryanodine receptor 2 in mouse cardiomyocytes.Immunocytochemical staining of mouse cardiomyocytes using Anti-SCN1A (NaV1.1) Antibody (#ASC-001), Anti-NaV1.5 (SCN5A) (1978-2016) Antibody (#ASC-013) and Anti-NaV1.6 (SCN8A) Antibody (#ASC-009) antibodies. All three neuronal NaV channels (green) co-localize with Ryanodine receptor 2.

- Anti-NaV1.5 (SCN5A) (493-511) Antibody (#ASC-005). This antibody recognizes a different epitope and can thus be used as a control for detecting NaV1.5.
- Guinea pig Anti-NaV1.5 (SCN5A) Antibody (#AGP-008) is raised in guinea pig and can be used in colocalization studies in conjunction with any of our antibodies raised in rabbit. This antibody has been raised against the same epitope as #ASC-005.
