    Scientific background

    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.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 domains (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

    Image & Title: Anti-Nav1.5 (SCN5A) (493-511) AntibodyDecreased expression of NaV1.5 in RyR2s/s atria.Immunohistochemical staining of mouse atria using Anti-NaV1.5 (SCN5A) (493-511) Antibody (#ASC-005), Anti-NaV1.6 (SCN8A) Antibody (#ASC-009) and Anti-SCN1A (NaV1.1) Antibody (#ASC-001). NaV1.5 staining in RyR2s/s atria is lower compared to wild type levels. NaV1.6 staining slightly decreased in RyR2s/s atria. NaV1.1 which is not expressed in the atrial tissue is not detected.Adapted from King, J.H. et al. (2013) with permission of Elsevier.

    Anti-NaV1.5 (SCN5A) (493-511) Antibody (#ASC-005) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunoprecipitation, immunohistochemistry, and immunocytochemistry applications. It has been designed to recognize NaV1.5 sodium channel from rat, human, and mouse samples.
