Subsequent Staining

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.

Tissue Extracts

A method based on the use of miniature ion-exchange columns has been devised for isolating small amounts of amino acids from biological fluids and tissue extracts. The amino acids are isolated virtually free from proteins, sugars, and inorganic cations in a single treatment.Techniques are described for the preparation of solutions of the isolated amino acids for quantitative analysis by paper chromatography.
