Tacrolimus hplc assay
WebThe QMS Tacrolimus Immunoassay is a homogeneous particle-enhanced turbidimetric immunoassay. The assay is based on competition between drug in the sample and drug coated onto a microparticle for antibody binding sites of the tacrolimus antibody reagent.

WebTacrolimus concentrations in whole blood samples can be determined using immunoassays or liquid chromatography–tandem mass spectrometry (LC-MS/MS). 4,6,8,9 Whole blood samples for quantitation of tacrolimus are usually obtained by venous sampling. WebTacrolimus (TRL)3 is a potent calcineurin inhibitor that is increasingly used for primary immunosuppression after liver transplantation because of its perceived advantages over cyclosporine (1, 2). Recent clinical practice has been to reduce the TRL dosage and side-effects by use of adjunctive therapy with mycophenolate mofetil, siroli-
