  • Process for the specific isotopic labeling of methyl groups of Val, Leu and Ile
    Patent number: 10053396
    Abstract: A process for the specific isotopic labeling of an amino acid selected from Valine (Val), Leucine (Leu), and Isoleucine (Ile), in proteins and biomolecular assemblies by introducing, in a medium containing bacteria overexpressing a protein, an acetolactate derivative of Formula I of the application.
    Type: Grant

  • Process for the specific isotopic labeling of methyl groups of Val, Leu and Ile
    Patent number: 9708228
    Abstract: The invention relates to a process for the specific isotopic labeling of Valine, Leucine and Isoleucine amino acids. The process of the invention uses a 2-alkyl-2-hydroxy-3-oxobutanoic acid in which the alkyl substituent in position 2 is ethyl or methyl. The invention can be used for the analysis of proteins, in particular by NMR.
