Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

G01N 33/53

US Classification:

435 71, 436518

Abstract:

The invention provides methods of preparing a test sample for use in an assay for detecting an analyte bound by an intracellular ligand. The methods typically involve contacting the test sample with an assay reagent comprising: a lysis reagent; and a protease that has proteolytic activity for said intracellular ligand; to form a mixture compatible for use in an immunoassay without subsequent extraction steps. Other aspects of the invention include related immunoassays and test kits.

US Classification:

5303898, 435 80, 435 81, 530421

Abstract:

An improved extractive reagent composition and method for extracting an immunosuppressant drug, such as sirolimus, tacrolimus or cyclosporine, from blood samples while yielding a test sample extract that has low vapor pressure and is compatible with immunoassay components. The inventive reagent composition comprises dimethyl sulfoxide (DMSO), at least one divalent metal salt and water. The sample extracts resulting from use of each of these combinations have low vapor pressure and are compatible with immunochemistry assays.
