温馨提示:为了达到最佳使用效果,材料应始终保持在干燥的低温条件下。避免频繁解冻和冻结。
二、结构式
三、描述
活性酯在PH7-8.5与伯胺基团反应形成稳定的酰胺键。聚乙二醇增加溶解度和稳定性,减少多肽和蛋白质的原性, 抑制带电分子在修饰表面的非特异性结合。可修饰蛋白质、多肽和其它小分子材料。应用于医药研究、药性缓释、纳米新材料研究、细胞培养。在活性化合物的配体研究,多肽合成载体,高分子接枝化合物,材料聚乙二醇涂层及修饰功能化方面应用成为研究趋势。
CLS - PEG - the NHS is a kind of different double functional group PEG derivatives, cholesterol is forms the foundation of liposome membrane and material, is an indispensable important material of animal tissue cells, which not only participate in the formation of the cell.Film, and is a synthesis of bile acid, vitamin D and leave the body produce raw materials. Cholesterol can adjust the liquidity of phospholipid bilayer membrane, reduce the membrane permeability, reduce drug leakage. At the same time maintain a certain flexibility, can make the lipid membrane enhanced liposome vesicle in the fight against external conditions change. And for the oxidation of phospholipids have certain protective effect. Active ester (NHS) PH7 8.5 react with primary amine groups to form stable amide bond. Through PEG connection of cholesterol has better solubility in water, PEG cholesterol derivatives can be used in the membrane imaging, liposomes, and drugs transmission.
