Iodination of proteins
WebAccording to our study iodine uptake is decreased in patients with diabetes mellitus which may be due to increased glycation of proteins. AB - Iodination is the process of substitution or addition of iodine atoms on organic compounds. The iodine is reactive with all the three major biochemical constituents namely proteins, lipids and carbohydrates.

WebThe results show that IPy(2)BF(4) has clear advantages over existing methods in that the reaction is quantitative, fast, and selective for the most accessible Tyr residues of a protein, and it preserves the functional integrity of the protein when moderate Tyr labeling levels are pursued. Iodination is a very useful method for protein characterization and labeling. WebIn comparative studies, the immunological activity after iodination by this method was equal to, or greater than, that by the chlorine gas, Iodo-Gen, or chloramine-T methods. A new method, employing the mild oxidant n-bromosuccinimide, for the iodination of proteins for radioimmunoassay is described. Human prolactin, follicle-stimulating, luteinising, thyroid …
