中文:胆固醇-聚乙二醇-马来酰亚胺(MW:2000)
英文:Cholesterol-PEG-Maleimide,CLS-PEG-MAL
所属分类:Maleimide PEG DSPE PEG
结构式:
简介:
CLS-PEG-MAL是马来酰亚胺修饰性PEG中的一种, 他可以用来修饰蛋白,抗体,多肽等。马来酰亚胺可以和巯基反应形成稳定的硫醚键。
Cholesterol is a membrane composition, have adjust the function of membrane fluidity, elasticity and permeability. When proteins embedded in the membrane, it fills the other space form the accumulation of lipid species.
Polyethylene glycol (peg), cholesterol, as a kind of amphiphilic lipid derivatives, can be used for the preparation of liposomes and other micelles as delivery system. Except the mPEG cholesterol, also can pass the custom synthesis activity or dye tag PEG cholesterol reagents, and the cycle is short.
该列表可能包括:胺聚乙二醇胆固醇、马来酰亚胺聚乙二醇胆固醇、FITC聚乙二醇胆固醇、生物素聚乙二醇胆固醇和NHS聚乙二醇胆固醇等。胆固醇通过稳定的酰胺键连接到聚乙二醇。
