Anti-TAG-1 antibodies are protein reagents that detect specific antigens. The TAG-1 antigen is another term for the human protein contactin 2, encoded by the CNTN2 gene. The protein is known to function in axon guidance and cell adhesion, among other biological roles. Canonically, it has an amino acid length of 1040 residues and a mass of 113.4 kilodaltons. Its subcellular localization is in the cell membrane and it is expressed in the cerebellum and cerebral cortex. The TAG-1 protein is a member of the Contactin protein family. Other alias names for TAG-1 include AXT, FAME5, and TAG-1. Indicated applications for TAG-1 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry.
