Anti-CLC2 antibodies enable researchers to detect and measure the CLC2 antigen in biological samples. This target is a reported synonym of the CLCN2 gene, which encodes chloride voltage-gated channel 2. This protein is known to function in acinar cell differentiation and lung development, among other biological roles. The human version of CLC2 has a canonical amino acid length of 898 residues and a protein mass of 98.5 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in many tissues, such as the adrenal gland and appendix. CLC2 is a member of the Chloride channel (TC 2.A.49) protein family.
