Project TitleSolubilizing Membrane Proteins without the Use of Detergent
Track Code2009-069
Short Description

A research tool to solubilize membrane proteins without detergent


Northwestern researchers have developed a novel method for isolating integral membrane proteins in a detergent-free manner.  This process offers the ability to isolate solubilized membrane complex in its native lipid environment with undisturbed changes in its composition and structure.  These attributes are particularly essential in providing a way to use and study membrane proteins in its native conformation.  Furthermore, it obviates the need for using synthetic lipid vesicles to handle membrane proteins.  This method produces a product that is a great alternative to liposomes as a mode of drug delivery for a number of reasons.  Not only are they smaller in size and more stable in shear flow, they diffuse faster and serve as a means to for surface attachment.
