Abstract

Tyrosine and cystine have been found to streak on paper chromatograms with almost all solvents. The phenotnenon has been traced to their sparing solubility in the aqueous as well as the solvent phases. Employtnent of amino acid solutions and of solvent systems rendered sufficiently acidic or alkaline helps to secure compact spots and adequate separations. Unidimensional development with pH 1.0. buffered phenol on similarly buffered paper is satisfactory for the quantitative estimation of the acids.
