Product Description
NSP offers heterobifunctional Folate-PEG-azide (Folate-PEG-N3) with high quality. Folic acid, or vitamin B9, can selectively bind to folate receptor, while azide group can react with alkyne in aqueous solution catalyzed by copper. The PEG moiety in the heterofunctional PEG derivatives provides water solubility, biocompatibility, and flexibility. This reaction allows attachment of folic acid ligand to proteins, antibodies, peptides or particle surfaces. Folic acid functionalized substrates have been used for targeted drug delivery, imaging, and bioassay development.
