Monoclonal antibodies reacting with murine teratocarcinoma cells.

Abstract
Monoclonal antibodies were produced in vitro by fusing mouse myeloma cells with spleen cells from a rat immunized with the C3H mouse teratocarcinoma C86.cntdot.S1. After the fusion 2 clones were chosen for further analysis. Clone 3C4-10 produced an antibody recognizing an antigen with a distribution restricted to teratocarcinoma cell lines, an endoderm cell line and a neuroblastoma. Clone 4A1-9 produced an antibody that reacted with all cultured murine cells tested and adult brain. Neither antibody reacted with preimplantation embryos. The 3C4-10 antibody recognized an antigen associated with proteins. The apparent MW of the 3C4-10 antigen was greater than 100,000.
