Membrane Protein Reconstitution in Liposomes

Liposomes (Creative Biolabs)

With a lipid bilayer structure, liposomes are a proper system to mimic cell membranes in many cases. Reconstitution of membrane proteins into liposomes, which forms proteoliposomes, can keep membrane proteins correctly folded with their native structures, activities, and functions. Reconstitution of membrane proteins into liposomes is never an easy task to accomplish, mainly due to the high propensity for membrane proteins to aggregate and the difficulty in the preparation of stable, homogeneous proteoliposomes in desired size. However, scientists in Creative Biolabs have rich knowledge and decades of experience in performing experiments in this particular area. We are professional in proteoliposome preparation from various starting materials, such as intact cells, membrane crude extracts, and membrane proteins already solubilized or reconstituted in micelles, bicelles, nanodiscs, amphipols, or other liposomes.

Membrane Protein Reconstitution in Liposomes

Based on our lipid screening platform, a large variety of lipids either synthesized or extracted from natural sources are available in Creative Biolabs. We can also dope the proteoliposomes with proper types and fractions of charged lipids, modified lipids, and other additives like cholesterols to stabilize the proteoliposomes and maximally keep the membrane proteins’ function in their native form. We can perform comprehensive detergent screening platform with various detergents to select the one that does not cause unfolding, destabilization, aggregation, or conformational change of the target membrane proteins. After the solubilization and purification, we will add a series of lipids to the micellar solution of your membrane proteins followed by removing the detergents via hydrophobic beads binding or dialysis.

Treatment after Membrane Protein Reconstitution in Liposomes

After the formation of proteoliposomes, occasionally further treatment is desired to change the proteoliposome size or change the liposome morphology.
