Phospholipid-PEG-Biotin (MW 3400)

Phospholipid-PEG-Biotin (MW 3400) is a heterobifunctional reagent used to biotinylate lipid membranes via its phospholipid anchor. Its PEG-linked biotin group enables strong, specific conjugation to avidin or streptavidin, facilitating the surface modification of liposomes for drug delivery and cells for transplantation studies in both in vitro and in vivo research.
