Online Inquiry

Creative Proteomics provides services to quickly and accurately identify a variety of amino acids in plant issues and systematically analyze the molecular mechanism, pharmacodynamics, and in vivo dynamics of amino acids. Our technology platform utilizes the latest analytical instruments, such as HPLC, LC-MS/MS, and automatic amino acid analyzer, to qualitatively and quantitatively analyze amino acids.


Amino acids are biologically important organic compounds, consisting of amino (-NH2) and carboxyl (-COOH) functional groups, as well as side chains connected to each amino acid. They are not only the raw material for protein synthesis but also participate in the regulation of various physiological functions of cells, which is essential for maintaining life. Amino acids can be classified into aliphatic amino acids, aromatic amino acids, heterocyclic amino acids, acyclic amino acids, basic amino acids, sulfur-containing amino acids, hydroxyl amino acids, iodine-containing amino acids, etc., according to their different binding groups.

Recent advances in gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) have deepened our understanding of metabolic regulation occurring in plant cells. We can efficiently separate amino acids and sort them based on different molecular masses to comprehensively conduct amino acid profiling in samples and apply them in several related research areas. The full spectrum of amino acids can reflect the balance of life activities and detect related dynamic changes, such as reflecting substance metabolism and immune regulation.
