Experimental Evidence for a Cluster Glass Transition in Concentrated Lysozyme Solutions
Lysozyme is known to form equilibrium clusters at pH ≈ 7.8 and at low ionic strength as a result of a mixed potential. While this cluster formation and the related dynamic and static structure factors have been extensively investigated, its consequences on the macroscopic dynamic behavior expressed by the zero shear viscosity η 0 remain controversial. Here we present results from a systematic in
