A Rapid iMethod™ Test for the Analysis of Four Immunosuppressant Drugs Utilizing Direct Injection LC/MS/MS iMethod™ Test for Immunosuppressants Version 1.0 for Cliquid® Software
The following description outlines the instrument requirements Samples are prepared using a protein precipitation step, and expected results obtainable from the AB SCIEX iMethod™ centrifuged then injected for LC/MS/MS analysis. Cyclosporin D Test for the analysis of four immunosuppressant drugs. This and Ascomycin are used as internal standards. Complete details method has been validated for use on either the AB SCIEX 3200 regarding the instrumentation and sample preparation are included with the iMethod™ Test. Extraction procedures for plasma are also similar and included in the method document This method is based on the analysis of Cyclosporine A, Tacrolimus, Sirolimus, Everolimus, and the internal standards Cyclosporine D and Ascomycin in whole blood. The method utilizes Chromsystems Whole Blood Calibrators and Whole Blood Controls for determination of Cyclosporine A, Tacrolimus, The chromatogram below is representative of the data acquired.

A level 0 – (blank level) containing zero concentration of each of cartridge kit are included with this iMethod™ Test. Also, that this the four analytes was also used. Concentrations of Calibrators method can also be run on other HPLC systems, given that they are supported for use by Cliquid® Software and the retention times are updated to reflect the configuration used. Note: Actual results obtained may vary due to variation in the LC column properties, chemicals, instrument performance, and Ordering Information
sample preparation procedures used. It is suggested that the method be fully validated prior to routine use. Product Name

iMethod™ Test for Immunosuppressants Version 1.0 This method was evaluated using the calibrators from the Chromsystems whole blood calibrator set (batch: Lot No. 2907) (Includes iMethod™ Test for Mycophenolic Acid Version 1.0 for Cliquid® and controls from the Chromsystems whole blood controls Levels I, II, III and IV (batch: Lot No. 1408). Accuracy, %CV and S/N values for the target analytes were obtained using 6 low level replicates of the Level 1 Calibrator. Accuracies range from 97-105% and %CVs 3.2-11.5. The estimated quantitation limits for each analyte are more than sufficient to allow the analytical method to be used for therapeutic drug monitoring. Intra-assay precision (n=6) for the low concentration QC was between 2.3 and 15.4%CV and accuracies between 93-99%. System Requirements
To run this method as provided, the following equipment is • An AB SCIEX API 3200™ or 3200 QTRAP® Systems • A Shimadzu Prominence 20A LC System or an Agilent 1100 • Cliquid® Software for Routine Analysis • Whole blood calibrators and controls can from Chromsystems • Standards for the four immunosuppressants: Cyclosporin A, Everolimus, Sirolimus (Rapamycin), and Tacrolimus • Internal standards: Ascomycin and Cyclosporin D • HPLC grade water and methanol • High purity ammonium acetate, formic acid, and zinc sulfate • Phenomenex SecurityGuard guard cartridge kit (guard column • Phenomenex SecurityGuard Luna C18 cartridge column, 4 • Vortex mixer • Pipettes and standard laboratory glassware Please note that the Phenomenex SecurityGuard Luna C18 cartridge column and Phenomenex SecurityGuard guard While the information provided above outlines the instrument requirements and expected results obtainable from the AB SCIEX iMethod™ Test for the Analysis of Immunosuppressants, please note that the results obtained do require some experience with LC/MS/MS and sample preparation procedures. As such, web-based and on-site training are available to assist in the deployment of the iMethod™ Test and are recommended for inexperienced users.
