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
