Liquid Chromatography–Tandem Mass Spectrometry Analysis of Folate and Folate Catabolites in Human Serum

We investigated matrix effects 43 in plasma by measuring peak areas in eight different plasma samples spiked after the protein precipitation step with 10 nmol/L of

Separate bench and blind QC pools with cotinine concentrations in the appropriate range were selected for use with high and low assays.. The tubes were capped and placed

The validated method is then applied to investigate the effect of fatty acids on the production of eicosanoids in fish liver cells, fish head kidney cells and human
