Abstract
A protein or peptide which has an amino-terminus serine or threonine which has an acetylated alpha-amino group is allowed to react with an acid, and then allowed to react with an isothiocyanate under acidic conditions to thereby obtain a thiocarbamyl compound. Then the compound is to be analyzed using Edman degradation. Analysis can be performed with fewer operation steps and without using enzymes.
