1,2-Distearoyl-phosphatidylethanolamine-methyl-polyethyleneglycol conjugate

DSPE-MPEG-2000 (Na+ salt)

This product has been used for creating micelles that are able to carry drugs with low solubility. DSPE-MPEG-2000 has proven exceptionally useful due to certain characteristics such as good stability, longevity, and ability to accumulate in areas with abnormal vasculature, including tumors2,3 which have leaky vasculature. This product can be enhanced by the addition of various groups such as attaching specific targeting ligand molecules, imaging agents or surfactants to further increase the solubility.1
