Detection of the HER-2/neu proto-oncogene protein p185erbB2 by a novel monoclonal antibody (MAB-145ww) in breast cancer membranes from oestrogen and progesterone receptor assays. Academic Article uri icon


  • Amplification of the proto-oncogene HER-2/neu and/or overexpression of the transmembrane protein p185erbB2 that it encodes occur in approximately 30% of human breast and gynaecological cancers seen clinically and are strongly associated with an unfavourable outcome. We report on the use of a new monoclonal antibody (Mab-145ww) together with immunoblotting for detection of p185erbB2 in membranes that remain after routine processing of breast cancer tissue for steroid receptor assays. Human breast cancer cell lines SKBR3 and MCF-7 were used as high and low controls, respectively, for p185erbB2 expression. Mab-145ww was detected p185erbB2 in more than half of the breast cancer specimens; the expression was intense in SKBR3 cells, but only faint in MCF-7 cells. These results demonstrate that routine processing of cancer tissue for steroid receptor status can include providing a preparation with which to assess p185erbB2 expression and, thus, can provide information potentially useful for the clinical management of individual cancer patients.
