Paper Chromatography of Proteins [PDF]

Nature, 1951
Franklin and Quastel1 have recently applied the technique of paper chromatography to proteins. Protein–haemin complexes were prepared, and the position of each protein on the chromatogram could thus be revealed by the benzidine reaction. The method has limited application since many proteins do not react with haemin.

Quantitative Paper Chromatography

Nature, 1948
WE have recently developed a simple method for quantitative assay of amino-acids on the paper partition chromatogram. The method is in all probability applicable to any class of substance which can be readily located by means of a sensitive colourreaction on paper. Several technical points of general interest have arisen in the course of the work.
