Abstract: A method for diagnosing or differentially diagnosing a cancer characterized by the presence of cancer cells in the pleural fluid of a mammalian subject, the method comprising contacting a sample of pleural fluid of the subject with colloidal magnetic particles coupled to a ligand which binds to a determinant on a cancer cell, but does not bind above a baseline threshold to other cellular and non-cellular components in pleural fluid; subjecting the pleural fluid-magnetic particle mixture to a magnetic field to produce a cell fraction enriched in ligand coupled-magnetic particle-bound cancer cells, if present in the pleural fluid; and analyzing the enriched fraction for the number of cancer cells in the pleural fluid. In certain aspects, this method involves preparing the pleural fluids for the above-noted method steps by, e.g., dilution of unprocessed pleural fluid. In certain aspect, the pleural fluid is subjected to the diagnostic method within 24 hours of withdrawal from the subject.

Abstract: Compositions, systems, and methods comprising circulating endothelial cells (CECs) are provided. The compositions described herein utilize isolated CECs, including compositions in a form that allows analysis of the CECs. The systems described herein utilize isolated CECs and an analytical tool or an output from an analytical tool. The methods described herein are related to the use of isolated CECs and analytical tools for providing information, to a health care provider or the CEC donor, that is relevant to the cardiovascular health of the CEC donor. Thus, the compositions, systems and methods described herein involve both a transformation (e.g., non-isolated CECs to isolated CECs, or isolated CECs to analyzed CECs) and a machine (e.g., isolation tools and analytical tools).

Abstract: Elevated number of Circulating Endothelial Cells (CEC) have been implicated in disease conditions associated with the formation or destruction of blood vessels such as acute coronary syndrome, thrombocytopenic purpura, sickle cell disease, sepsis, lupus, nephrotic syndromes, rejection of organ transplants, surgical trauma and cancer. This invention provides a method for assessing the levels of CEC which vary between different studies using a sensitive enrichment, imaging, and enumberation analysis. CD146 is one of the most specific endothelium-associated cell-surface antigens which can be used in image cytometry. CEC analysis provides an essential tool in prognostic/diagnostic evaluation in the clinic.

Abstract: A method and composition for the purpose of detecting and measuring analytes, such as antibodies, which are capable of binding with certain binding partners such as antigens. A homogenous assay is performed in the presence of free unbound antibodies. Such a homogeneous assay testing for specific antibodies is herein possible by defining of test subsets of microparticles having specific antigens thereon which are capable of binding with specific target antibodies. The microparticle suspension also includes at least two calibration subsets of microparticles having a binding partner thereon with at least two known levels of concentration which is capable of binding with human antibodies for the purpose of assay calibration. A verification subset of microparticles is included with another binding partner thereon at a known concentration, capable of binding with anti-human antibodies.
