ABSTRACT:
Compositions and methods for use thereof relating to monoclonal antibodies, and fragments thereof, having inhibitory activity towards the cell-activating function of the complement C5b-9 complex. The compositions can be used in vitro to inhibit C5b-9 related stimulatory responses of platelets and/or endothelial cells, thereby preventing C5b-9-initiated cell necrosis or stimulated secretion of proteolytic enzymes and the exposure of the procoagulant membrane receptors during collection and in vitro storage. Further, disease states can be treated by administering to platelets and/or endothelial cells in vivo an effective amount of a monoclonal antibody, or fragment thereof, which has inhibitory activity towards the cell-activating function of the C5b-9 complex, in a pharmaceutically acceptable carrier.
