Abstract
IN the course of work on the extraction of iodinated tyrosines from human plasma and their subsequent estimation, it was necessary to determine the losses which might occur during the series of manipulations. For this purpose we decided to add quantities of [131I]-3-monoiodo-tyrosine ([131I]-MIT) and [131I]-3,5-diiodotyrosine ([131I]-DIT) small enough to be below the lower limits of estimation by our method but having a sufficiently high [131I]-activity to bo counted easily in a well-type scintillation counter.
