Importance of Amino Acids

Analysis of amino acids is required in several areas of research, and it is a fundamental tool in product analysis. The application imposes different requirements on the analytical method because the amino acids play different roles.

• Amino acids are the basic constituents of proteins. Qualitative and quantitative analysis of the amino acid composition of hydrolyzed samples of pure proteins or peptides is used to identify the material and to directly measure its concentration
• Amino acids are also intermediates in metabolic pathways, often not directly involving proteins. The amino acids are measured as elements of physiological and nutritional studies. This has proven particularly important in monitoring the growth of cells in cultures, as used in the production of biopharmaceuticals
• Similar considerations lead to the analysis of foods and feeds to ensure that nutritional requirements are met

With the UPLC Amino Acid Analysis Solution, you benefit from better resolution and sensitivity, all achieved in a shorter analysis time than with conventional methodologies:

• Method robustness minimizes variability
• Better resolution translates into accurate results
• UPLC delivers greater throughput than traditional HPLC
• Protein characterization accelerates for comparison of amino acid composition deduced from the gene sequence for a product or its natural counterpart
• Monitoring cell culture media for critical nutrients allows you to optimize expression efficiencies and to make timely product harvesting decisions
• Avoid costly reformulations primary nutritional components

Optimized Peak Identification

AccQ•Tag™ Ultra Chemistries used in the UPLC Amino Acid Analysis Solution are a comprehensive and fully-tested set of reagents, columns, and eluents optimized for use with the ACQUITY UPLC H-Class and ACQUITY UPLC H-Class Bio Systems. With superior resolution of all amino acids, you will confidently achieve peak identification and quantitation, which in turn assures the accuracy of your results.

This chemistry is based on Waters’ widely-used and understood AccQ•Tag derivatizaton method. Primary and secondary amino acids react with a single reagent, AccQ•Fluor™, in a high-throughput batch process resulting in exceptionally stable derivatives. High resolution separations are achieved using pre-qualified AccQ•Tag Ultra UPLC columns and mobile phases. Derivatized amino acids are quantified to sub-picomole levels with single wavelength UV detection.

Determination and control of critical nutrients in cell culture is important to maximize protein yield and provide a consistent manufacturing process. The Waters UPLC^®Amino Acid Analysis (AAA) Solution is a turnkey solution that provides accurate, high throughput amino acid analysis.

The UPLC Amino Acid Analysis Solution meets the specific demands of analyzing amino acids for protein characterization, cell culture monitoring, and nutritional analysis of foods and feeds. This end-to-end system is designed to deliver the accuracy and reliability you need to be successful.
