The present invention provides a nanodisc with a membrane scaffold protein. The nanodisc includes a membrane scaffold protein, a telodendrimer and a lipid. The membrane scaffold protein can be apolipoprotein. The telodendrimer has the general formula PEG-L-D-(R)
n
, wherein D is a dendritic polymer; L is a bond or a linker linked to the focal point group of the dendritic polymer; each PEG is a poly(ethylene glycol) polymer; each R is and end group of the dendritic polymer, or and end group with a covalently bound hydrophobic group, hydrophilic group, amphiphilic compound, or drug; and subscript n is an integer from 2 to 20. Cell free methods of making the nanodiscs are also provided.
本发明提供了一种具有膜支架蛋白的纳米盘。该纳米盘包括膜支架蛋白、端酯聚合物和脂质。膜支架蛋白可以是载脂蛋白。端酯聚合物具有通式PEG-L-D-(R)n,其中D是树枝状聚合物;L是与树枝状聚合物的焦点基团连接的键或连接物;每个PEG是聚乙二醇聚合物;每个R是树枝状聚合物的末端基团,或具有共价结合的疏水基团、亲水基团、两性化合物或药物的末端基团;下标n是2到20之间的整数。还提供了制备纳米盘的无细胞方法。
