High resolution membrane protein structures using Salipro® and CryoEM

Salipro® and CryoEM

 

Cryo-electron microscopy (cryoEM) is a cutting-edge technique used in drug discovery and structure-based drug design, as it can deliver key information on drug targets.

The Salipro® technology has been used to solve numerous high resolution structures of membrane proteins with cryoEM.

The images below showcase several of these structures, consisting of the membrane protein (yellow) and Salipro® scaffold protein (blue). In some cases, the membrane protein is bound to ligands (other colors). Click on the images below to learn more.
