Quality Control for Amino Acid Visualization Reagents
A method is described that quantitatively evaluates development conditions and reactivity of amino acid visualization reagents. Ninhydrin was the primary reagent used in this study. The method consists of spotting a serial dilution of amino acids in a numbered grid on paper. Examples of the variability of development as a result of atmospheric conditions are illustrated.
