LT-85 is an alveolegenic adenocarcinoma induced in mutant C3HfB/HeN (C3Hf) mice. This tumor, however, grows preferentially in allogeneic, wild-type C3H/HeN (C3H) mice. The tumor-associated transplantation antigen has been mapped to the K end of the major histocompatibility complex. H-2K antigens were isolated from detergent extracts of LT-85 cells by immunoprecipitation with monoclonal antibody. The tryptic peptides of these antigens were compared, by using high-pressure liquid chromatography, with the tryptic peptides of H-2K antigens isolated from syngeneic mutant C3Hf and ancestral wild-type C3H spleen cells. We found that the H-2K antigens of the LT-85 tumor cells were very similar to, but distinct from, those present on syngeneic C3Hf lymphoid cells. We also found, however, that the H-2K antigens of LT-85 tumor cells were clearly different from the H-2K antigens of allogeneic C3H spleen cells. The H-2K antigens of LT-85 cells are therefore foreign to syngeneic C3Hf cells, but do not represent expression by the tumor cells of the allogeneic H-2K antigens expressed by normal C3H cells. Furthermore, the nature of the differences observed between the H-2K antigens of LT-85 cells and C3Hf and C3H spleen cells strongly suggests that the structure of the H-2K molecule of LT-85 cells is identical in some regions to the H-2K molecule of C3Hf cells, and in other regions to the H-2K molecule of C3H cells.
