Anti-Pre T-cell Antigen Receptor Alpha antibodies enable researchers to detect and measure the Pre T-cell Antigen Receptor Alpha antigen in biological samples. This target is a reported synonym of the PTCRA gene, which encodes pre T cell antigen receptor alpha. The human version of Pre T-cell Antigen Receptor Alpha has a canonical amino acid length of 281 residues and a protein mass of 29.3 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the membrane of cells.
