Naturevolume 199pages10021003 (1963) | Download Citation



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.
