This application note describes a simple ISOLUTE® PPT+ protocol for the extraction of methylmalonic acid (MMA) from serum, demonstrating high, reproducible analyte recoveries with low protein content in the extracts. ISOLUTE PPT+ Protein Precipitation plates offer a fast and extremely simple sample preparation approach. Serum proteins are efficiently removed from the sample using an in-plate, ‘solvent first’, protein crash and filter procedure, which is easily automated using the Biotage Extrahera system. Details of the automated procedure and data comparing manual and automated method performance are included.

•Extends the range of acidic, basic and neutral compounds that can be extracted using a single generic method, increasing method development productivity•Has an optimized pore structure which reduces the extraction of endogenous matrix components, and leads to cleaner extracts that give fewer matrix effects in LC-MS/MS analysis•Has optimized physical and chemical characteristics that improve reliability of SPE procedures•Has no secondary interactions, allowing the use of pure organic elution solvent to give high recoveries of very low drug concentrations

Protein precipitation is a routinely used sample preparation technique for removal of proteins from biological fluid samples prior to analysis. Protein precipitation in the 96-well format, using filtration for protein removal, is a high throughput alternative to the traditional centrifugation based technique.
