    摘要： The CellTracks® System provides a system to enumerate circulating melanoma cells in blood. The system immunomagnetically concentrates epithelial cells, fluorescently labels the cells and identifies and quantifies circulating melanoma cells. The absolute number of circulating melanoma cells detected in the peripheral blood tumor load is, in part, a factor in prediction of survival, time to progression, and response to therapy. Diagnosis and monitoring of melanoma has been limited by the inability to monitor circulating melanoma cells. The present invention provides a method to enumerate circulating melanoma cells in blood samples. Accordingly, this technology provides a means and device for monitoring disease progression in patients with melanoma.

    摘要： A highly sensitive assay is disclosed which combines immunomagnetic enrichment with multiparameter flow cytometric or image cytometry to detect, enumerate and characterize carcinoma cells in the blood. The present invention incorporates the conjugation of different antibodies to the same ferrofluid. This has the effect of making the ferrofluid polyspecific with respect to the antigens that the ferrofluid will bind. The multiple antibodies present on the same ferrofluid do not appear to block or otherwise interfere with each other. Such ferrofluids have the highly desirable effect of being able to bind specifically to more than one type of cell. The assay is especially useful to enable the capture of CTCs that have low EpCAM expression, but high expression of other tumor markers; Accordingly, the assay facilitates the biological characterization and staging of carcinoma cells.
