[14C] DL-phenylalanine and [35S]DL-methionine were resolved using cellulose column chromatography. The assignment for the resolved enantiomers was carried out by means of co-chromatography with non-labeled oL-amino acids after modification with fluorodinitrobenzene. The optical purity of the enanti
