title: Engineered proteins with desired specificity: DARPins, other alternative scaffolds and bispecific IgGs.
abstract: Specific binding proteins have become essential for diagnostic and therapeutic applications, and traditionally these have been antibodies. Nowadays an increasing number of alternative scaffolds have joined these ranks. These additional folds have raised a lot of interest and expectations within the last decade. It appears that they have come of age and caught up with antibodies in many fields of applications. The last years have seen an exploration of possibilities in research, diagnostics and therapy. Some scaffolds have received further improvements broadening their fields of application, while others have started to occupy their respective niche. Protein engineering, the prerequisite for the advent of all alternative scaffolds, remains the driving force in this process, for both non-immunoglobulins and immunoglobulins alike.
