Amino Acid Standard

Description

• Application: This analytical standard was used as follows:Determination of L- and D-amino acids and glycine by liquid chromatography-tandem mass spectrometry (LC-MS/MS) following their derivatization with chiral Marfey’s reagentHigh-performance liquid chromatography (HPLC) based amino acid analysis during the characterization of defatted rice bran (DRB) protein concentrate to evaluate its iron binding abilityDevelopment of a gas chromatography-mass spectrometry (GC-MS) procedure for the profiling of 112 amino-carboxylic metabolites in human urine samples using 1,1,1,2,2,3,3-heptafluorobutyl chloroformate for derivatization and liquid-liquid microextraction for sample treatmentNon-enantiomeric detection and quantification of amino acids in their various forms— free, dissolved, particulate, and total, in natural water samples by HPLC coupled with fluorescence detection using a C18 column
• Packaging: 1 mL size packaged in flame sealed ampules.
• Components: The following components are included in the amino acid standard:L-AlanineAmmonium chlorideL-ArginineL-Aspartic acidL-CystineL-Glutamic acidGlycineL-HistidineL-IsoleucineL-LeucineL-LysineL-MethionineL-PhenylalanineL-ProlineL-SerineL-ThreonineL-TyrosineL-Valine
