Abstract: Whole cell, simultaneous target and drug-target assay using differentially labeled antibodies and flow cytometry. First antibody binds to total target and second antibody binds to the drug binding site of the target, thus drug binding will competitively inhibit the second antibody allowing for a competitive inhibition assay of drug-target binding. The assay allows for whole cell analysis and even analysis of mixed populations of cells, yet provides detailed kinetic assessment of drug activity.

Abstract: A new method of cell fixation using a mild denaturing heat and the fixative PERMIFLOW™ or similar fixative that preserves cell morphology, light scatter profiles, nucleic acid content, cell surface epitopes and unmasks internal epitopes previously not available. The method can be combined with analysis of each of these parameters by flow cytometry and thus has application in drug screening and patient or tumor monitoring protocols.

Abstract: Kits are provided that can be used to determine a thromboxane B2 metabolite level and a creatinine level in a biological sample, particularly a human urine sample. This information can be used to optimize aspirin dosage in a patient. The present invention further includes calibrant preparations. In some embodiments, these calibrants comprise urine, particularly human urine that is identified in repeated trials to provide a consistent and reproduceable level of thromboxane B2 metabolite. As such, they function as control preparations that reduce error from intra-assay sampling measurements.

Abstract: Disclosed are unique methods for identifying the lowest, yet optimal, aspirin doses for patients. These methods are also characterized as having little to no aspirin-related side-effects. These methods may be used pre- as well as post-thrombotic event, and employs a patient's urinary thromboxane B2 metabolic levels (e.g., 11-dehydrothromboxane B2), to identify the patient's platelet activation level. A patient's urinary thromboxane B2 metabolic level is then used to calculate and appropriate and individualized treatment effective for utilizing platelet activation. Kits for utilizing this technique are also provided. In yet another particular aspect, the invention provides a method for utilizing a random urine sample obtained from a patient to determine whether a patient or particular individual's current dosage of aspirin is providing an adequate and appropriate level of inhibition of platelet activation levels, as compared to inhibition levels observed in individuals not taking aspirin.

Abstract: This invention relates to methods of analyzing a tissue sample from a subject. In particular, the invention combines morphological staining and/or immunohistochemistry (IHC) with fluorescence in situ hybridization (FISH) within the same section of a tissue sample. The analysis can be automated or manual. The invention also relates to kits for use in the above methods.
