An antiserum prepared by injecting C3H/HeJ mice with CBA/J tissue has been shown to react with cell surface components that are not part of any previously described system of serologically detectable alloantigens. The antiserum, which is designated AST-101, acts selectively in cytotoxic tests carried out with lymphoid cells, killing B cells, but not T cells. Phagocytic cells found in peritoneal exudates are also killed by AST-101 and complement in vitro; the sensitivity of other cell types has not been determined. Strain distribution does not indicate any association of the AST-101 system with H-2, Ly, or Thy systems; genetic analysis reveals close linkage with the mouse minor MLC-stimulating (Mls) locus. Serologic analysis also points to a close association between antigens reactive with AST-101 and the products of the Mls genes.
