Anti-SNS-2 antibodies enable researchers to detect and measure the SNS-2 antigen in biological samples. This target is a reported synonym of the SCN11A gene, which encodes sodium voltage-gated channel alpha subunit 11. This protein is known to function in neuronal development, among other biological roles. The human version of SNS-2 has a canonical amino acid length of 1791 residues and a protein mass of 204.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include FEPS3, HSAN7, and NAV1.9.
