The glutathione (GSH) synthesis inhibitor, buthionine sulfoximine (BSO) was tested for cytotoxicity and thiol depletion in murine and human tumor cells in vitro, and for its antitumor activity and toxicity in vivo. The cell lines used in these studies included murine L-1210 leukemia, human RPMI 8226

We have tested the tumoricidal potency of enzyme immunotoxins constructed of antibodies conjugated to glucose oxidase and to lactoperoxidase. Murine plasmacytoma cells were targeted in vitro with the use of affinity-purified rabbit anti-plasmacytoma membrane antibodies (conjugated to glucose oxidase

Small fragments of silicone gels injected intraperitoneally have been used to induce plasmacytomas in genetically susceptible mice. Silicone oils, in contrast to silicone gels, are apparently not tumorigenic in the mouse plasmacytoma system. The reason for this difference as well as the mechanism of

Screening assays are the most time-consuming and labor-intensive part of generating monoclonal antibodies (MAbs). Antibodies identified by enzyme-linked immunosorbent assay (ELISA) screening often are not suitable for their intended application such as immunofluorescence staining. We describe here a
