This application note describes a simple, effective protocol for the extraction of methylmalonic acid (MMA) from serum using ISOLUTE® SAX strong anion exchange solid phase extraction plates, demonstrating high, reproducible analyte recoveries with low protein and phospholipid content in the extracts. Very clean extracts are possible due to the purely anion exchange retention mechanism available using this silica based sorbent. This minimizes the co-extraction of endogenous interferences through hydrophobic (or non-polar) retention. The method can be easily automated using the Biotage Extrahera. Details of the automated procedure and data comparing manual and automated method performance are included.

Immunosuppressant drugs are instrumental in preventing organ and tissue rejection in patients undergoing transplant surgery. Mycophenolic Acid is a common immunosuppressant drug used in patient transplant therapy. The ability to monitor the trough levels in patients to evaluate dosing is important for the administering of the drug. The free drug and its glucuronidated metabolite can be found in patient serum. The ability to extract the free drug and metabolite in patient serum is supported by using a fast and efficient sample preparation extraction method called Supported Liquid Extraction (ISOLUTE SLE+). The free drug and metabolite can be recovered from serum using ISOLUTE SLE+ with high enough efficiency to allow for quantitation at target trough levels. MSACL 2014
