Abstract
BY means of filter-paper partition chromatography, Fink, Dent and Fink1 located several different radioiodine fractions in hydrolysates prepared from thyroids of rats that had been injected 24–28 hours earlier with iodine-131. Surprisingly, little or none of the radioactivity was found as thyroxine. Since this is not in accord with previous results from this laboratory2, we examined the method of filter-paper chromatography as applied to thyroid iodine.
