Goal
Development of a robust, reliable, and reproducible workflow solution for the analysis and quantitation of immunosuppressant drugs in blood for clinical research using triple quadrupole mass spectrometry coupled with ultra-high performing liquid chromatography.

Application benefits
- Development of a robust workflow for the analysis and quantitation of immunosuppressant drugs in blood with an ultra-high performing liquid chromatograph (UHPLC) and Thermo Scientific™ TSQ Fortis™ triple quadrupole mass spectrometer (QqQ)
- Leveraging enhanced performance of a robust QqQ with the sensitivity needed to develop a robust, reliable, reproducible quantitative workflow
Introduction
Starting with cyclosporine A, several immunosuppressant drugs have been developed and introduced, including the macrolides tacrolimus, sirolimus, and everolimus (Figure 1).
