Quantitation of polyamines using thin-layer chromatography and image analysis.


Efficient separation of dansylated polyamines can be achieved by thin-layer chromatography (TLC). Quantitation, however, can be laborious because it requires removal of the silica gel and the fluorescing derivative from the glass plates, elution in a suitable solvent, and estimation with a fluorescence spectrophotometer. We report here a relatively simple… (More)
