Folate-PEG-CH2CO2H, MW 3,400 is a polyPEG which can react with amine (in the presence of activator, such as HATU or EDC) to form an amide linkage. The folic acid terminus can strongly bind with folate receptor in neutral pH and transports them into cells. This property enables site specific delivery of therapeutic agents in a drug delivery system. Reagent grade, for research purpose.
