well as one or two mannose units. The carbohydrate-lectin interaction in this artificial, self-assembled glycocalyx was monitored in an agglutination assay by the increase of optical density at 400 nm. It was found that there is a close relation between the carbohydrate density at the cyclodextrin vesicle surface and the multivalent interaction with ConA, and the most efficient interaction (i.e., fastest
环糊精囊泡是生物细胞膜的通用模型,因为它们提供了双层膜,可以通过主客体与功能性客体分子的相互作用轻松修饰。在本文中,我们研究了凝集素伴刀豆球蛋白 A (ConA) 与环糊精囊泡的多价相互作用,环糊精囊泡装饰有带有一个、两个或三个金刚烷单元以及一个或两个甘露糖单元的甘露糖-金刚烷缀合物。在凝集试验中,通过增加 400 nm 处的光密度来监测这种人工自组装糖萼中的碳水化合物-凝集素相互作用。发现环糊精囊泡表面的碳水化合物密度与与 ConA 的多价相互作用之间存在密切关系,并且最有效的相互作用(即,
