Cellsome made from Cationic PEGylated Lipids(DSPC:Chol:DSTAP:DSPE-PEG2k)

DSPC:Chol:DSTAP:DSPE-PEG(2000) (55:30:10:5 molar ratio),DSTAP-PEG2000 (1,2-distearoyl-3-trimethylammonium-propane PEG) has a cationic head group (positively charged) that can bind to negatively charged biomolecules (such as nucleic acids or cell membranes) through electrostatic interactions, while the PEG chain provides hydrophilicity and steric hindrance effects, reducing immune clearance. PEGylation forms a "stealth" effect, reducing serum protein adsorption and clearance of the mononuclear phagocytic system (MPS), and prolonging the half-life in vivo.
