Absence of Free Iodotyrosines from the Plasma of the Rat

Abstract

WERNER et al.1,2 and Beale and Whitehead3 have recently claimed to have demonstrated the presence under physiological conditions of free 3 : 5-di-iodotyrosine (DIT) and 3-iodo-tyrosine (MIT) in the serum of euthyroid human beings and rats using paper chromatographic separation followed by several methods for the detection and estimation of iodine1–5, a distinctive feature of these serum iodotyrosines being that they could not be labelled with radioiodine.
