Abstract

The invention relates to a method and reagent mixture for the staining and thus visualization of amino acids, peptides and similar compounds, in particular after separation by means of thin-layer chromatography. The staining is carried out using ninhydrin for the detection of amino acids, peptides or proteins in combination with at least one ionic liquid.
