Voltage-Gating Device (VGD) for Cryogenic Electron Microscopy (Cryo-EM)

Princeton Docket# 19-3561-1 Electric fields are widely used to switch nanoelectronics devices and can be precisely controlled by a variety of power sources. There are extensive studies of how electric gating affects materials’ physical properties, but it is still unclear, in most cases, how electric fields/currents change the structures or...

Compositions and Methods for Regulating Intramembrane Proteases

Princeton University Invention # 07-2348 Intramembrane proteolysis is a widely conserved regulatory mechanism in species ranging from bacteria to humans. The first description of intramembrane proteolysis came from the investigation of cholesterol homeostasis, where the ER membrane-bound transcriptional factor SREBP must be cleaved by an...
