A Robust LC/MS/MS Method for the Quantitation of Very Long Chain Fatty Acids for Research into the Characterization of Peroxisomal Disorders

The peroxisome is a cellular organelle that plays an important role in a number of functions, including the beta-oxidation of very long chain fatty acids (VLCFA). Peroxisomal disorders are characterized by impaired, reduced or total absence of peroxisomes in cells, which can result in the accumulation of VLCFAs, such as tetracosanoic and hexaco...

A new LC/MS/MS Research Method for Rapid Quantitation of Five Immunosuppressant Drugs, including Mycophenolic Acid (MPA)

A previously published application note in this series describes an LC/MS/MS method for the simultaneous determination of four immunosuppressant drugs: Cyclosporin A (CsA), Tacrolimus (TAC, aka FK-506), Sirolimus (SIR, aka Rapamycin) and Everolimus (EVE, aka RAD-001) (1, 2). The method is based on a simple and robust hardware configuration and...
