This application note describes the extraction of a panel of steroid hormones from human serum using ISOLUTE® SLE+ Supported Liquid Extraction plates prior to LC/MS-MS analysis. The simple sample preparation procedure delivers clean extracts and high, reproducible recoveries (>75%, RSD <10% ) for all analytes in human serum, with linearity >0.99 in the range 5–5000 pg/mL.

This application note describes the extraction of testosterone and androstenedione from female patient serum samples using ISOLUTE® SLE+ (96 well) plates. This method has been optimized to extract testosterone and androstenedione from female clinical serum samples. The method has achieved very low limits of quantitation for testosterone and androstenedione 0.4nmol/L and 0.9nmol/L respectively. The recoveries for both analytes were greater than 90%.

This application note describes the extraction of testosterone and other steroid hormones from human plasma using ISOLUTE SLE+ supported liquid extraction plates (96-well) with LC-MS/MS analysis. This method describes the use of ISOLUTE SLE+ supported liquid extraction plates (96-well) to extract a range of steroid hormones including testosterone and progesterone from human plasma. This simplified and efficient extraction method has significant analyte recoveries ranging from 90-107% withb LOQs as low as 500 pg/mL.

This poster demonstrates a rapid and reliable sample preparation method using Supported Liquid Extraction (ISOLUTE SLE+) to extract a suite of 30 hormone analytes from a hydrolyzed urine matrix. Single injection analysis by LC-MS/MS shows that matrix effects are eliminated by the ISOLUTE SLE+ protocol and that analyte recovery and sensitivity have excellent clinical utility.
