Correct estimation of protein concentration in aqueous biological samples is an essential step in biochemical research and the pharmaceutical industry impacting downstream applications. Infrared (IR) spectroscopy is a powerful and growing analytical tool for the detection and analysis of biomedically relevant compounds such as proteins, lipids, carbohydrates, and nucleic acids. While AAA can be used to determine the quantities of individual amino acids,
the amino acid ratio or composition and it is regarded as the gold
standard for protein and peptide quantification. APAF can offer both these services.
