Detection of Iodine-containing Compounds on Paper Chromatograms

A new reagent for detection of peptides, nucleotides, and other N-H-containing compounds on paper chromatograms.

The detection of small quantities of nitrogen-containing compounds on paper chromatograms is a problem of long standing interest. The ninhydrin technique, first introduced by Consden, Gordon, and Martin (l), has partially solved this problem and has proven to be extremely valuable. However, the narrow range of compounds detected, the decreased sensitivity with increased molecular weight of pept...
