Anti-Nav1.4 antibodies enable researchers to detect and measure the Nav1.4 antigen in biological samples. This target is a reported synonym of the SCN4A gene, which encodes sodium voltage-gated channel alpha subunit 4. This protein is known to function in the transport of ions, among other biological roles. The human version of Nav1.4 has a canonical amino acid length of 1836 residues and a protein mass of 208.1 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include CMS16, CMYP22A, and HOKPP2.
