Researchers at Shimadzu Corporation in Japan and Nobuyuki Tanaka, the winner of the 2002 Nobel Prize in Chemistry, have newly developed a protein analysis technique in late May 2004 that can quickly identify protein types by understanding protein fragmentation information. Proteins consist of chains of hundreds or more amino acids. When the new technology analyzes a certain protein, it seals the sample in a mass analyzer device, detects only about 10 amino acids of the protein, and analyzes the type of amino acid chain, etc., and then obtains the information and protein analysis database. Control, determine the protein type. The new method can greatly improve the efficiency of protein analysis. Proteins are the basis of life activities. Effective analysis of proteins is very helpful in identifying difficult diseases. Therefore, this result has attracted considerable attention in the field of biotechnology in Japan.
