: a reaction of ninhydrin with amino acids or related amino compounds used for the colorimetric determination of amino acids, peptides, or proteins by measuring the intensity of the blue to violet to red color formed or for the quantitative determination of amino acids by measuring the amount ...
Later Ruhemann (3) and Grassmann and von Arnim (1) have shown that the color-forming reaction of ninhydrin with amino acids is accompanied with the evolution of COO. Both Van Slyke (4) and Dillon and Mason (2) have devised methods for the determination of amino acids based on the ...
Ninhydrin Reaction Medical The following article is fromThe Great Soviet Encyclopedia(1979). It might be outdated or ideologically biased. a color reaction used for the qualitative and quantitative identification of amino acids, imino acids, and amines. Upon heating in an alkaline medium with substanc...
Occult fingerprints are sometimes made visible by the use of ninhydrin, which turns purple due to reaction with amino acids present in perspiration. Fingerprints or other marks are also sometimes made visible by exposure to high-powered laser light. Some fingerprints can be treated with chemical ...

of material from sections. 0.2 N NaOH slightly reduced staining after the ninhydrin-Schiff procedure at all sites in rat skin. The interpretation of this finding is obscure, because some sites giving a positive Sakaguchi reaction and staining with anionic dyes failed to stain after the ninhydrin-...
