Radioiodinated antibody targeting of the HER-2/neu oncoprotein.

Journal Article

The HER-2/neu oncogene encodes a 185 kDa phosphoglycoprotein that is overexpressed in breast, ovarian and other cancers. Seven monoclonal antibodies reactive with oncoprotein were labeled with 131I. In vitro experiments with SKOv3 9002-18 cells determined binding affinity, internalization and degradation. The biodistribution of these antibodies in comparison to 125I-labeled nonspecific antibody was measured in athymic mice with SKOv3 9002-18 ovarian carcinoma xenografts. Antibody 520C9 exhibited the highest and most specific retention in tumor, peaking at 17.4 +/- 5.6% ID/g at 24 h.
