A solvent redeveloping technique has been devised by which amino acids, peptides, and sugars can be separated from complex mixtures in the presence of high concentrations of salts and proteins. The separations are effected by two to four successive 18-hour solvent developments with drying between each 18-hour period before subsequent staining of the chromatograms. Better separations and resolutions are obtained by such successive 18-hour solvent developments than by one continuous solvent development for an equivalent time. The effect of these redevelopments on the separations and resolutions of biological compounds is illustrated at various stages by photographs of one- and two-dimensional chromatograms. The redevelopment technique requires filter paper sheets up to 4 ft in length for one-dimensional analytical and preparative types of chromatograms.

The use of a solvent redevelopment technique enables the separation of amino acids from complex biological materials in the presence of high concentrations of salts. By conventional chromatography, 1.17 mg of total amino acids have been separated from the high salt medium M 150. The preparative technique as described here has separated amounts as great as 1.17 g and the patterns are essentially the same as for the analytical types. The separations are effected by four or more successive 15- to 20-hour solvent developments with drying between each solvent stage before the staining of chromatograms or isolation of particular bands. The results of these solvent developments on the preparative scale are illustrated with photographs of actual chromatograms. This technique requires thick filter paper sheets up to 4 ft in length for analytical, and particularly for preparative, chromatograms.

Chromatographic Methods

A colorimetric ninhydrin method has been applied to the quantitative estimation of amino acids and peptides on paper chromatograms. This method is suitable for the analysis of enzymic transpeptidation reactions. A procedure for the purification of filter paper for chromatography has been developed.
