Expression of protozoan antigens by hybrids between Leishmania mexicana and myeloma SP2/0.

Hybrid cells were obtained between Leishmania mexicana promastigotes and mouse myeloma SP2/0 cells, and examined for expression of leishmanial antigens. A ratio of 1:10 of myeloma to T. cruzi cells was unsuccessful because of outgrowth of non-fused cells.
