✦ Synopsis

The thin-layer chromatographic behaviour of a series of N-thiobenzoylamino acid anilides (TBA-amino acids) has been studied. Techniques for the separation of these derivatives by thin-layer chromatography have been established, permitting the identification of a T&X-amino acid obtained in a cycle of a new stepwise degradation of polypeptides.

Model experiments with bovine insulin have demonstrated the efficiency'of au N-terminal analysis method in which the N-terminal amino acid residue of a polypeptide is isolated as its TBA-derivative, and identified as such by thin-layer chromatographic techniques.
