Paper Abstract

The formation of macromolecular protein clusters in the presence of some heavy ions was observed by the Rayleigh light scattering and polarized fluorescence methods. Luminescence spectra of europium chelate and BAS-europium chelate water solutions were obtained at different pH and concentrations of components. The rotational correlation time of particles in the solutions containing heavy ions increase significantly in comparsion with rotational correlation time of protein macromolecule. This result can be explained by macromolecule clusters formation.
