The amount of free e-amino groups of lysine residues in proteins can be determined by a fast and straightforward method based on the use of r9F NMR spectroscopy. Unsubstituted e-amino groups are trifluoroacetylated with the reagent, S-ethyl trifluorothioacetate, in dimethyl sulfoxide solution, and t
A procedure using 2,4,6-trinitrobenzenesulfonic acid (TNBS) for the determination of epsilon-amino groups in soluble and poorly soluble proteinaceous materials is presented. The major modification from previous procedures is an extended TNBS reaction time to allow a stoichiometric reaction with amin
