Abstract
Indirect immunofluorescence and radioimmuno‐assay with specific rabbit antisera demonstrated the occurrence of alphafetoprotein (AFP), carcino‐embryonic antigen (CEA) and placental alkaline phosphatase (PLAP) in primary testicular tumor cells. Embryonal carcinomas had AFP‐ and CEA‐containing cells, sometimes PLAP. PLAP and sometimes CEA were found in seminoma cells. Sera from patients with advanced non‐seminomatous tumors could contain any of these antigens or any combination of them. Sera from patients with seminomas had raised PLAP or CEA. PLAP appears to be a new marker for seminoma.
