A cytotoxic protein expressed by human peripheral blood mononuclear cells is isolated in essentially homogenous form. This protein may be used to elicit production of polyclonal or monoclonal anti-cytotoxin antibodies. n Hybridomas secreting anti-cytotoxin antibodies are identified by a solid phase bioassay. The antibodies are useful in the immunopurification of cytotoxins. The purified cytotoxic proteins are useful for the treatment of virus-infected or tumor target cells, either alone or in combination with interferon or a metabolic blocker. |
