STUDIES OF THE INFLUENCES OF PROTECTOR DTT AND SENSITIZER MISO ON THE RADIATION-INDUCED BIOMOLECULAR FREE RADICAL REACTIONS BY THE SPIN TRAPPING ESR METHOD.

DTT is scavenger of H2O free radical (OH, H and eaq) and can markedly decrease the yields of radiation-induced radical of dT (Thymidine). MISO is a transfer carrier of eaq in aqueous solution, hence it can expand the radius of action of eaq, and can increase the yields of dT free radical.
