Background: TRA-1-85/CD147

The TRA-1-85 antigen, also known as OKa blood group antigen, is a specific epitope within the protein known as Basigin, EMMPRIN and CD147. It is a cell surface determinant expressed on almost all human cell types. This antibody has been used in somatic cell hybrid studies to identify tissues of partial human origin (1, 2).
