Anti-RCAD antibodies enable researchers to detect and measure the RCAD antigen in biological samples. This target is a reported synonym of the CDH4 gene, which encodes cadherin 4. This protein is known to function in axon guidance and cell adhesion, among other biological roles. The human version of RCAD has a canonical amino acid length of 916 residues and a protein mass of 100.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells.
