PEG-bis-amine (MW 1000)

PEG-bis-amine (MW 1000) is used to synthesize folate-conjugated polymer micelles that encapsulate the anticancer agent 9-nitrocamptothecin. These folic acid-conjugated polymer micelles effectively deliver insoluble anticancer drugs, evading macrophages and facilitating endocytosis by tumor cells through folate receptors (FR) .
