11dhTxB2 Test Kit (11-Dehydro Thromboxane B2) 12136

GUDID 00855360006274

INTENDED USE The 11dhTxB2 Test Kit is an enzyme-linked immunoassay (ELISA) to determine levels of 11-Dehydro Thromboxane B2 (11dhTxB2) in human urine which aids in the qualitative detection of acetylsalicylic acid (ASA) effect in apparently healthy individuals post ingestion. For In Vitro Diagnostic Use. SUMMARY OF THE ASSAY Activated platelets produce Thromboxane A2 (TxA2), a potent vasoconstrictor and inducer of platelet aggregation. TxA2 is generated by Thromboxane synthase from molecules derived from arachidonic acid by cyclooxygenase-1 (COX-1). TxA2 has a short half-life in plasma and is rapidly hydrolyzed to Thromboxane B2 (TxB2). TxB2, in turn, is metabolized to 11-Dehydro Thromboxane B2 (11dhTxB2).The measurement of stable metabolites of TxA2, such as urinary11dhTxB2, is a means of quantitating TxA2 production in vivo and thus a direct way to analyze ASA’s effect post ingestion. PRINCIPLE OF THE TEST The 11dhTxB2 Test Kit measures urinary 11dhTxB2 and is performed as a competitive ELISA. Diluted samples (Reference Solution, controls, and patient urine), purified 11dhTxB2 conjugated to alkaline phosphatase (AP), and purified mouse monoclonal antibody directed to 11dhTxB2 are combined and incubated in microwells coated with a polyclonal anti-mouse antibody. The monoclonal antibody then binds to the polyclonal anti-mouse antibody coated on the microtiter plate. After the removal of unbound complexes by washing, the bound AP-11dhTxB2 conjugate is assayed by the addition of para-nitrophenylphosphate (pNPP) chromogenic substrate. Color develops in the wells at an intensity inversely proportional to the sample urine concentration of 11dhTxB2, and is read at 405nm. Results (pg/mL) are calculated against a reference curve prepared from the Reference Solution provided in the kit. Final results are reported as pg 11dhTxB2 per mg creatinine to normalize results for urine concentration. Refer to product package insert.
