MATERIALS AND METHODS RELATING TO THE INCREASE IN PROTEIN ACTIVITY

摘要

The invention provides a protein framework which allows active polypeptides e.g. ligands or antigens to be displayed at increased concentration. The inventors show that the lectin binding domains of collectins can be replaced by a polypeptide of interest and that polypeptide can be multimerised by the framework of the collectin and as a result displayed in greater number on a single structure. The inventors show that the activity of polypeptides such as those of the TNF superfamily are significantly enhanced when displayed in this way.
