DSPE-PEG-Biotin, MW 5K is a linear heterobifunctional PEGylation reagent with DSPE phospholipid and biotin. It is a useful self-assembling reagent to prepare graft or PEGylated liposome or micelle while providing an biotin group for binding to avidin or streptavidin. It is useful in targeted drug delivery with the lipid bilayer to improve drug solubility. PEG provides stealth property, extend circulation half-life and reduce non-specific protein binding.
