[Quantitative dansyl micromethod of amino acid analysis. Study of peptide maps of ribonuclease tryptic hydrolysate].

Some variants of the quantitative dansyl method in combination with thin-layer chromatography on polyamide plates have been compared, and principles of its optimization have been demonstrated. Sensitivity of the method is about 10(-11) mole, the error does not exceed 10%. Data are given on the analysis by the dansyl method of peptides of the tryptic hydrolysate of bovine pancreatic ribonuclease after their separation by peptide mapping procedure.
