Thin-layer chromatography of trinitrophenyl derivatives of amino acids in urine and plasma.
The preparation and separation by thin-layer chromatography of the trinitrophenyl derivatives of amino acids in plasma and urine is described. The semi-quantitative procedure presents a useful addition to existing methods for screening biological fluids for aminoacidopathies.
