Anti-KCNAB2 antibodies are used in the immunodetection of the protein potassium voltage-gated channel subfamily A regulatory beta subunit 2. In humans, the canonical protein has a reported length of 367 amino acid residues and a mass of 41 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is notably expressed in myelinated nerve fibers in the spinal cord, in the juxtaparanodal region of the nodes of Ranvier, but also in the paranodal region. It is a member of the Shaker potassium channel beta subunit protein family. Synonyms for this target antigen include HKvbeta2, HKvbeta2.1, HKvbeta2.2, KCNA2B, KV-BETA-2, and AKR6A5. KCNAB2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of KCNAB2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
