R-C-259	DSPE-PEG2000-benzylguanine	Peg is a linear polymer material which is polymerized by ethylene glycol monomer. In PEG lipid complex,due to the weak connection between PEG or PEG stearic acid and liposome,it can not effectively reduce the uptake of res to liposome.The ability of PEG dipalmitoyl phosphatidylglyceride and PEG cholesterol to prolong the half-life of liposomes was stronger than that of PEG or PEG stearic acid alone,but lower than DSPE-PEG.Peg and DSPE are connected by carbamate bond,and there are two saturated acyl chains.The lipophilic end is DSPE and the hydrophilic end is peg.The connection between PEG and DSPE is firm, and the ability to protect the liposome from being destroyed is the strongest.	price>
