Publication number: US6187547
Abstract: A new method of measuring blood levels of immunophilin-binding pharmaceuticals, e.g., cyclosporins, rapamycins, and FK506 compounds is provided, comprising the novel step of displacing the pharmaceutical from its immunophilin by using a binding competitor, thereby eliminating the need for an extraction step and enhancing the simplicity and accuracy of the assay. Assay kits comprising a binding competitor and a receptor, e.g., a monoclonal antibody, which binds to the pharmaceutical but not significantly to the binding competitor are also provided, as are new uses of immunophilin-binding compounds as binding competitors in such assays.
