Anti-Cdh28 antibodies enable researchers to detect and measure the Cdh28 antigen in biological samples. This target is a reported synonym of the CDHR3 gene, which encodes cadherin related family member 3. This protein is known to function in cell adhesion, among other biological roles. The human version of Cdh28 has a canonical amino acid length of 885 residues and a protein mass of 98 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the nasopharynx, fallopian tube, and bronchus.
