The occurrence of low levels of thrombin action in ACD bank blood was indicated by the presence of small clumps of fibrin in electron microscope specimens prepared from blood stored for 5 or more days. The case for investigating the possibility that low level thrombin action is a significant factor in shortening the survival of red cells during storage may be based on 1 the change of behavior of fresh red cells during the natural activation and action of thrombin 2 the indication that thrombin cleaves a peptide bond in a membrane-associated protein 3 the demonstration that low levels of thrombin action occur in ACD bank blood. The demonstration that low levels of thrombin action do occur in stored blood and reduce the mechanical strength of red cells provides a basis for designing studies to incorporate thrombin inhibitors to increase the storage life of bank blood.
