Haemoglobin stabilization during lyophilization with saccharides. Perturbation effect of polyethylene glycols

Abstract
The stabilizing effect of glucose and sucrose upon haemoglobin molecules against oxidation during lyophilization was perturbated by the presence of fluid or greasy polyethylene glycols (m.w. 300-600 daltons) but not of the rigid ones (m.w. 1 500-6 000 daltons). The results corroborate the idea of a simple mechanical nature of haemoglobin stabilization under study.
