A two-dimensional ion-exchange thin-layer chromatographic method is described for the separation of all methylated basic amino acids from biological fluids or protein hydrolysates; development is carried out on Fixion 50-X8 plates, which contain a resin of the Dowex 50-X8 type. An automatic amino acid analyzer was used for quantitative analysis of the minor basic amino acids.
