Plasma methylmalonic acid
WebMethylmalonic acid is extracted from 250 μl serum/EDTA plasma into ethyl acetate along with the internal standard: ethylmalonic acid (EMA). 73 To achieve sufficient assay sensitivity it is necessary to generate fluorescent derivatives of these analytes with dicyclohexylcarbodiimide prior to their separation by reversed phase HPLC with an ... WebMethylmalonic acid (MMA) is extracted from plasma or serum along with an added internal standard using a commercially available strong anion exchange resin (1). The extracted acid is then derivatized with cyclohexanol to form a dicyclohexyl ester. The derivatized samples are injected onto a gas chromatograph for separation from other constituents.
