[HTML][HTML] Detergent-free isolation and characterization of cholesterol-rich membrane domains from trans-Golgi network vesicles

MG Waugh, KME Chu, EL Clayton, S Minogue… - Journal of lipid …, 2011 - ASBMB
Cholesterol is an abundant lipid of the trans-Golgi network (TGN) and of certain endosomal
membranes where cholesterol-rich microdomains are important in the organization and
compartmentalization of vesicular trafficking. Here we describe the development of a rapid
method to isolate a cholesterol-rich endomembrane fraction. We show that widely used
subcellular fractionation techniques incompletely separate cholesterol-rich membranes,
such as the TGN, from organelles, such as late endosomes and lysosomes. To address this …
