A novel high-throughput screen for identifying lipids that stabilise membrane proteins in detergent based solution.
Membrane proteins have a range of crucial biological functions and are the target of about 60% of all prescribed drugs. For most studies, they need to be extracted out of the lipid-bilayer, e.g. by detergent solubilisation, leading to the loss of native lipids, which may disturb important protein-li...

Membrane proteins have a range of crucial biological functions and are the target of about 60% of all prescribed drugs.

Relipidation of membrane proteins has proven extremely successful for studying challenging targets, but the identification of suitable lipids can be expensive and laborious. Therefore, we developed a screen to aid the high-throughput identification of beneficial lipids.
