In experimental part of the task two methods of oxidative iodination of hyaluronic acid modified by tyramine with the lowest degree of modification ( HA - TM - 1 ) was examined. Chloramine method, used as first one, turned out ineligible as due to presence of oxidative agent in the phase with hyaluronic acid a partial degradation of the sequence occurred. Another method of iodination with the use of iodogen is heterogenous reaction, oxidative agent is present as an insoluble deposit on the walls of the reaction vial. This method of radiolabelling was more moderate to hyaluronic acid.
