Analysis of Amino Acids by HPLC with fluorescence detection after precolumn derivatization with OPA/ mercaptoethanol.Kehr, J
High performance liquid chromatography (HPLC) on reverse-phase, silica-based supports has revolutionized protein-sequencing analytical procedures. It provides rapid, sensitive, quantitative analysis of phenylthiohydantoin (PTH) amino acids formed during the Edman degradation of proteins and peptides. It is...
Accurate amino acid composition analysis for HPLC, UHPLC, and UPLCAccurately separating, identifying, and quantitating amino acids is challenging. The amino acid sequence is the primary structure of a protein and it is unique to a particular peptide or protein. Amino acids are also key ingred...
