Zheng G, Li H, Zhang M, Lund-Katz S, Chance B, Glickson JD Bioconjugate chemistry, 2002 DOI: 10.1021/bc025516h To target tumors overexpressing low-density lipoprotein receptors (LDLr), a pyropheophorbide cholesterol oleate conjugate was synthesized and successfully reconstituted into the low-density lipoprotein (LDL) lipid core. Laser scanning confocal microscopy studies demonstrated that thisContinue Reading
