Non-ionic detergents are key reagents for the characterization of membrane protein drug targets. Suitable detergents are commonly identified by trial and error, which leads to failed preparations and raising costs. Recent findings suggest that not only the chemistry of detergents but also the strategy with which detergents and proteins are brought together impact the successes of investigations. To facilitate the future development of non-ionic detergents in membrane protein research, herein, we review chemical design concepts and detergent exchange strategies for a successful integration of detergents into the analysis of challenging membrane protein complexes. Our overview reveals exciting opportunities to tackle existing challenges, including the stabilization of G-protein coupled receptors, the development of fluorinated detergents for studying protein-lipid binding, top-down design of detergents, and hybrid detergents for the identification of non-canonical lipid associations to proteins with relevance to antibiotic research. Our review will facilitate the development of chemical tools for the biophysical characterization of membrane proteins and support the discovery of biological findings in the future.
非离子型去污剂是用于表征膜蛋白药物靶点的关键试剂。合适的去污剂通常是通过反复试验来确定的，这会导致制备失败并增加成本。最近的研究结果表明，不仅去污剂的化学性质，而且去污剂与蛋白质结合的策略都会影响研究的成功率。为了促进非离子型去污剂在膜蛋白研究中的未来发展，在此，我们综述了化学设计概念和去污剂交换策略，以便成功地将去污剂整合到具有挑战性的膜蛋白复合物分析中。我们的综述揭示了应对现有挑战的令人兴奋的机会，包括G蛋白偶联受体的稳定、用于研究蛋白质-脂质结合的氟化去污剂的开发、去污剂的自上而下设计以及用于鉴定与抗生素研究相关的蛋白质非经典脂质关联的混合去污剂。我们的综述将促进用于膜蛋白生物物理表征的化学工具的开发，并支持未来生物学发现的探索。
