Abstract
We have utilized a high-diversity phage display library to engineer antibody fragments (Fabs) that can modulate the activity of the enzyme isocitrate dehydrogenase 1 (IDH1). We show that a conformation-specific Fab can reactivate an IDH1 mutant associated with …

Abstract
Phage display is commonly used to identify and isolate binders from large combinatorial libraries. Here we present phage selection protocols enabling generation of synthetic antibodies capable of recognizing multiprotein complexes and conformational states. The procedure describes stages of the experiment design, optimization, and screening, …

Abstract
Structural determination of membrane proteins is extremely challenging due to the physical characteristics of membrane proteins themselves and the lack of adequate tools and technologies to perform the studies. Recent developments in micro-focus X-ray beams, novel detergents, protein thermo-stabilization, and protein engineering have been essential in …
