Monoclonal blood grouping sera provide a means of overcoming difficulties inherent in the use of conventional polyclonal reagents. Two murine monoclonal anti-Lewis reagents were tested and found to be comparable to conventional reagents for use in red cell phenotyping. These reagents may detect Le(a) antigen on Le(a-b+) red cells with greater sensitivity than previously available polyclonal anti-Lewis reagents.

Lewis (y) antigen, a difucosylated oligosaccharide, has been shown to be associated with malignant properties of ovarian carcinomas. In this study, we have investigated the potential role of Lewis (y) antigen, which was stably transfected into ovarian cancer RMG-1 cells, on carboplatin-induced apoptosis. Overexpression of Lewis (y) antigen effectively protected vitronectin-adherent RMG-1 cells from carboplatin-induced apoptosis as assessed by Hoechst 33258 staining and flow cytometry.

Unlabelled: Radioimmunotherapy (RIT) of solid tumor is often limited in efficacy because of restrictions in achieved tumor dose. In an effort to overcome this, the combination of RIT with other therapeutic modalities was investigated in an animal model of breast carcinoma. The rationale for this combined-modality RIT (CMRIT) was to increase the therapeutic efficacy of RIT through the use of paclitaxel to arrest cells in the radiosensitive G(2)/M phase of the cell cycle.

Purpose: Monoclonal antibodies and tyrosine kinase inhibitors specific for the epidermal growth factor receptor (EGFR) have been shown to enhance the effect of external beam radiation on EGFR-positive tumors. The effect of EGFR signaling abrogation by EGFR tyrosine kinase inhibitor on the efficacy of radioimmunotherapy has not been reported previously. This study investigated the effect of EGFR tyrosine kinase inhibition on the efficacy of radioimmunotherapy in a human cancer xenograft model.

Unlabelled: Absorbed doses in (90)Y radioimmunotherapy are usually estimated by extrapolating from (111)In imaging data. PET using (86)Y (beta(+) 33%; half-life, 14.7 h) as a surrogate radiolabel could be a more accurate alternative.

The humanized complementarity determining region-grafted anti-Lewis Y (Le(y)) monoclonal antibody [humanized 3S193 (hu3S193)] was developed for targeting Le(y)-expressing epithelial tumors such as breast, colon, lung, prostate, and ovarian carcinoma. We are exploring the potential use of smaller molecular size, bivalent analogues of hu3S193, because the faster blood clearance of M(r) approximately 54,000 diabody and M(r) approximately 110,000 F(ab')(2) molecules may be advantageous in achieving optimal and rapid tumor uptake for diagnostic and potential therapeutic applications. The single-chain variable fragment-5 residue linker construct (diabody) was expressed using the bacterial secretion vector pPOW3, and soluble product was purified without refolding processes.
