The F(ab)2 fragment of Me1-14, a murine IgG2a monoclonal antibody directed against proteoglycan chondroitin sulfate-associated protein expressed by gliomas and melanomas. By binding to proteoglycan chondroitin sulfate-associated protein, monoclonal antibody Me1-14 F(ab’)2 conjugated to a radioisotope may localize gliomas and melanomas when used as a tracer in radioimaging applications; in radioimmunotherapeutic applications, this agent conjugated to a radioisotope may be used to deliver targeted radiotoxicity to these tumors.
