In the present study we examined the influence of the solvent viscosity on the migration rate of the quencher anthraquinone sulfonate through myoglobin towards an excited Zn protoporphyrin molecule at the binding site of the protein.

Particularly, anthraquinone-2,7-disulfonic acid showed a high affinity with a binding constant of 1.5 x 10 (5) M (-1) in 10 mM phosphate buffer, pH 7.0.

Quenching was also observed by anthraquinone sulfonate.

It has previously been shown that the rates and activation energies for migration molecules of different sizes through myoglobin are very similar.
