聚乙二醇衍生物4-Arm PEG-DSPE,四臂-聚乙二醇-磷脂
2022-08-02 22:33:00 【XYBMWCR】
中文:四臂-聚乙二醇-磷脂(MW:5000)
英文:4-Arm PEG-DSPE
1、分子量:5k,4-Arm PEG-DSPE其他分子量可以定制(4-Arm PEG-DSPE,MW:5000、4-Arm PEG-DSPE,MW:2000、4-Arm PEG-DSPE,MW:1000等)
2、质量控制:95%+
3、储藏条件:-20℃的冷冻箱中,以便于长期保存,惰性气体保护避光、干燥,原液应避免反复冻融循环。
4、物理性质:固体或液体取决于分子量。由于4臂聚乙二醇- dspe具有较大的疏水基团,该试剂在水溶液中的溶解性较差,在醚中的溶解性增强。
5、Access: now with active, filling the gas, after taking timely in the fridge.
6、Usage: use only for scientific research experiments.
4 arm - PEG - DSPE is a kind of contains four same branched chain of PEG derivatives, DSPE (1, 2-2 stearoyl - sn - glycerol - 3 - ethanolamine phosphate) is a kind of 18 carbon saturated phospholipids, commonly used in the synthesis of liposome. Polyethylene glycol (PEG) coupling DSPE is hydrophilic, can be used for drug delivery, gene transfection and biological molecules. Polyethylene glycol (peg) of phospholipids well to improve the blood circulation time and stability of the capsule drugs.
四臂聚乙二醇衍生物属于支链聚乙二醇。多臂聚乙二醇衍生物是常用的给药系统。改性后的药物分子量增加,不易被体内代谢所消除。此外,改性药物在体内的分散性和溶解性也会得到改善。多臂聚乙二醇衍生物也可以修饰生物材料的表面或形成新的生物医学材料。
