Amino Acid Analysis (AAA) Online Inquiry

If an exact knowledge of protein/peptide quantities is required for further applications, quantitative amino acid analysis, qAAA, is a suitable assay, which can not only determine protein quantities precisely, but also provide detailed information regarding the relative amino acid composition and free amino acids. The AAA procedure includes hydrolysis, separation, detection and quantification.

Amino Acid Analysis (AAA)

Hydrolysis is typically achieved under acid conditions. A standard procedure is hydrolysis with 6 M hydrochloric acid (24 hours, 110°C). Fragile amino acids, especially tryptophan and cysteine, will be partially destroyed. And then hydrolyzed samples (amino acids) are derivatized pre-column or post column for sensitive detection, separated by RP/SCX column. The use of internal and external standards of known amount is crucial for accurate quantification of each amino acid.

Protein characterization, concentration, content, molar ratio, and extinction coefficients can all be determined by using our amino acid analysis services.
