Abstract [en]

The use of combinatorial protein engineering to design proteins with novel binding specificities and desired properties has evolved into a powerful technology, resulting in the recent advances in protein library selection strategies and the emerge of a variety of new engineered affinity proteins. The need for different protein library selection methods is due to that each target protein pose different challenges in terms of its availability and inherent properties. At present, alternative engineered affinity proteins are starting to complement and even challenge the classical immunoglobulins in different applications in biotechnology and potentially also for in vivo use as imaging agents or as biotherapeutics. This review article covers the generation and use of affinity proteins generated through combinatorial protein engineering. The most commonly used selection techniques for isolation of desired variants from large protein libraries are described. Different antibody derivatives, as well as a variety of the most validated engineered protein scaffolds, are discussed. In addition, we provide an overview of some of the major present and future applications for these engineered affinity proteins in biotechnology and medicine.
