Isolation of a natural cytotoxic IgM "antibody" in human serum sensitizing L cells to complement.
An IgM fraction of human serum was isolated and purified. A portion of this fraction firmly attaches to L cells' surfaces, which sensitizes these cells to the lytic action of low concentrations of serum C. It contains the natural cytotoxic "antibody" to L cells.
