New "super albumin" technology can improve the treatment of bleeding disorders
The Adaptive Immunity and Homeostasis research group, headed by Jan Terje Andersen at the Department of Immunology, has developed a unique biomedical technology that can be used to create coagulation factors with a significantly longer duration of action than what is the case today. They have designed super albumin, which is a protein variant that can be coupled to protein-based drugs, and allow them to remain in the bloodstream for a considerable longer time.
