Description
Cys-GE11 is an N-terminal modified GE11 (HY-P10128) with cysteine (Cys) added. Cys-GE11 can be coupled through the thiol group of Cys. Cys-GE11 can be linked to PEG-P (TMC-DTC) through the N-terminus of cysteine to form a targeted polymer. Cys-GE11 can target cells with high EGFR expression (such as SMMC-7721 cells). Cys-GE11 can significantly enhance drug enrichment at the tumor site and exhibit low toxicity[1]
