Abstract
Poor prognosis of ovarian cancer, the deadliest of the gynecologic malignancies, reflects major limitations associated with detection and diagnosis. Current methods lack high sensitivity to detect small tumors and high …

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 …

Abstract
Antibodies that bind RNA represent an unrealized source of reagents for synthetic biology and for characterizing cellular transcriptomes. However, facile access to RNA-binding antibodies requires the engineering of effective …

Abstract
Engineering monovalent Fab fragments into bivalent formats like IgGs or F(ab’)2 can lead to aggregation presumably because of nonspecific off-target interactions that induce aggregation. In an effort to further understand the molecular determinants of nonspecific interactions for engineered antibodies and natively folded …

Abstract
A major challenge in membrane biophysics is to define the mechanistic linkages between a protein’s conformational transitions and its function. We describe a novel approach to stabilize transient functional states of membrane proteins in native-like …

Abstract
Reversible, high-affinity immobilization tags are critical tools for myriad biological applications. However, inherent issues are associated with a number of the current methods of immobilization. Particularly, a critical element in phage display sorting is functional immobilization of target proteins. …
