STUDY OF INTERACTION OF HOECHST 33258 WITH DNA AND HUMAN SERUM ALBUMIN UNDER THE INFLUENCE OF MILLIMETER RANGE ELECTROMAGNETIC WAVES

Abstract

In this work the effect of millimeter range electromagnetic waves (MM EMW) with the frequency 64.5 GHz on the complexes of Hoechst 33258 (H33258) with DNA and human serum albumin (HSA) has been studied by the methods of absorption and fluorescence spectroscopies. It was shown that the irradiation results in weakening of H33258 interaction with both macromolecules, which is connected with the fact that the frequency 64.5 GHz, being resonant for water, leads to the structurizing of water component around DNA and HSA, due to which the binding becomes weaker. This conclusion is based on the values of both binding constants and Stern–Volmer constants.
