WebJun 7, 2024 · Most tightly bound lipids are located at the periphery of proteins, where density maps are poorer in quality, and are typically outcompeted by detergent molecules used during standard purification processes. University of Illinois scientists have recently characterized these tightly bound lipids using a novel technique. WebMETHODS at present used for staining bound lipids either give an inadequate result histologically or depend on chemical reactions not characteristic of lipids as a class.
