Folate-PEG-CH2CO2H, MW 1,000 can bind to folate receptor on the surface of a broad spectrum of cancer tissue. The polymer can be used to design nanoparticles-based targeted cancer therapy via folate receptor which minimizes nonspecific uptake in normal cells. The terminal carboxyl can react with amine in the presence of HATU or EDC. Reagent grade, for research purpose.
