LCP Lipids

Membrane protein crystallization using lipidic cubic phase (LCP) is proving to be a successful methodology for obtaining good quality diffracting crystals from membrane proteins due to its membrane native-like environment [1].

Monoolein is the first choice lipid for performing an LCP crystallization experiment. However, since the nature of the lipid determines the nature of the LCP, it’s worth varying the LCP characteristics by screening different lipids, especially when initial crystallization attempts with monoolein have failed [2,3].

The LCP Host Lipids listed below are suited to form a stable lipidic cubic phase for membrane protein crystallization.
