Dissolve sodium metabisulfite in 50 mM sodium phosphate, pH 7, at a concentration of 12.6 mM (240 pg/100 pi). Prepare fresh. Approximately 100 pi of this solution is required for a 5-pg protein iodination. [Pg.424]

General protein iodination however, such intracellular protein iodination does not take place without the addition of huge amounts of H2O2 to the thyroid preparation. Moreover, the concentrations of methima-zole necessary to relieve the XI effect are 10 times higher than those inhibiting protein iodination (Pereira et al., 1990). [Pg.309]

The protein iodination procedure described here was introduced by Fraker and Speck (1978) and is an efficient solid-phase method for labeling exposed tyrosine residues under relatively mild conditions. [Pg.302]

In Table 2a are listed a number of receptors which both produce a PI response and, by the criteria mentioned above, seem to produce their major effects on target tissues through effects on the intracellular Ca " concentration. Most have been listed and reviewed previously (2), but thyrotrophin deserves some special comment since it is a hormone whose effects are usually ascribed mainly to activation of adenylate cyclase (see 32). Although this is undoubtedly correct, there is also some evidence that certain effects of thyrotrophin, particularly stimulation of glucose oxidation and of protein iodination, are triggered by a Ca " influx into thyroid cells (45). [Pg.453]

Nutrient deficiencies—Many animal studies have linked nutrient deficiencies, especially of the trace elements, to the development of cancer. Furthermore, deficiencies of vitamins A, C, E, and the B-complex vitamins have been associated with the increased susceptibility of chemically-induced tumors in animals, as have protein, iodine, iron, magnesium, and selenium deficiencies. [Pg.161]

Carrier-free iodine-125 for protein iodination is available from different manufacturers in an aqueous solution containing sodium hydroxide or sodium sulfite with the activity claimed to be in the form of iodide. This may be true of freshly prepared solutions but in the course of a few weeks significant amounts of this iodide activity is transformed into unidentified species. These species may be volatile and do not exchange with added iodide even after the addition of sodium sulfite or sodium thiosulfate. The uncertainty of the chemical properties of these species essentially eliminates the direct application of chemical methods for analysis (27). Inasmuch as iodine-125 is produced by neutron-irradiation of xenon the isotopic impurities are limited to iodine-126 and iodine-127. It turns out that the total amount of iodine in an iodine-125 solution is represented primarily by iodine-125 and iodine-127 with only a negligible amount contriuted by iodine-126. The nuclides iodine-125 and iodine-127 were determined by measuring the iodine-126 and iodine-128 formed by thermal neutron activation of a sample. [Pg.21]
