Anti-Kv4.3 antibodies enable researchers to detect and measure the Kv4.3 antigen in biological samples. This target is a reported synonym of the KCND3 gene, which encodes potassium voltage-gated channel subfamily D member 3. This protein is known to function in the transport of ions and protein oligomerization, among other biological roles. The human version of Kv4.3 has a canonical amino acid length of 655 residues and a protein mass of 73.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. Other names for this target antigen include BRGDA9, KCND3L, and KCND3S. Indicated applications for Kv4.3 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
