Membrane Proteins

Eurofins DiscoverX isolates full-length membrane proteins with the highest levels of purity while retaining their structural and functional integrity. They represent a vital class of biomolecules, serving as gatekeepers and mediators of cellular communication. GPCRs, for instance, are a diverse family of transmembrane receptors that play a pivotal role in cell signaling and are key drug targets. Ion channels and transporters regulate the flow of ions and molecules across membranes, impacting numerous physiological processes. All purified membrane proteins are sold in their full length and in their native conformity to lead successful research in terms of drug screening, antibody discovery, and vaccine formulation.Discover our ready-to-use membrane proteins.
