transmission electron microscopy, which revealed the formation of two populations of aggregates with diameters of 8–50 nm and 80–300 nm. When mixed with the classical detergent n-dodecylmaltoside (DDM), the four hybrids were well soluble and formed small mixed micelles. DDM/hybrid mixtures were further evaluated for the extraction of the full-length, wild-type human GPCR adenosine receptor (A2AR), and the
合成了四种具有麦芽糖极性头的杂化双链表面活性剂。非极性结构域由氢化链和由部分长度的全氟化核终止的丙基氢化间隔基制成的部分氟化链组成。发现它们的水溶性低于1g / L,而与两条链的长度无关。通过动态光散射和透射电子显微镜研究了纯杂种在水中的自组装特性,揭示了两个直径为8–50 nm和80–300 nm的聚集体的形成。与经典洗涤剂n混合时-十二烷基麦芽糖苷(DDM),这四个杂种具有良好的溶解性,并形成小的混合胶束。进一步评估了DDM /杂交混合物的全长野生型人GPCR腺苷受体(A 2A R)和细菌转运蛋白AcrB的提取。A 2A R的增溶显示萃取效率为40%至70%,而AcrB的萃取效率达到60-90%。最后,当作为添加剂存在时,三个杂种表现出显着的热稳定性。与C的衍生物12 -hydrogenated链和C 4 ˚F 9 -fluorinated链成为最有力的添加剂表现出的两个良好提取率2A
