Anti-EA2 antibodies are protein reagents that detect specific antigens. The EA2 antigen is another term for the human protein calcium voltage-gated channel subunit alpha1 A, encoded by the CACNA1A gene. The protein is known to function in chemical synaptic transmission and the regulation of intracellular calcium, among other biological roles. Canonically, it has an amino acid length of 2506 residues and a mass of 282.6 kilodaltons. Its subcellular localization is in the cell membrane and it is expressed in the liver, duodenum, and cerebellum. The EA2 protein is a member of the Calcium channel alpha-1 subunit (TC 1.A.1.11) protein family. Other alias names for EA2 include APCA, APCA, and BI. Indicated applications for EA2 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
