DSPE-PEG 2000 (Distearoylphosphatidylethanolamine-polyethylene glycol 2000)（Cat No.:I043452）is a lipid-based compound commonly used in drug delivery systems, particularly in liposomal formulations. The DSPE component enhances the stability and biocompatibility of the liposomes, while the PEG 2000 segment provides a hydrophilic layer that improves circulation time and reduces immune recognition. This makes DSPE-PEG 2000 ideal for targeted drug delivery, particularly in cancer therapy, as it enables controlled release of therapeutic agents and minimizes side effects. Its unique structure helps enhance the pharmacokinetics and efficacy of encapsulated drugs.
