Disposition and Pharmacology of a GalNAc3-conjugated ASO Targeting Human Lipoprotein (a) in Mice Rosie Z Yu, Mark J Graham, Noah Post, Stan Riney, Thomas Zanardi, Shannon Hall, Jennifer Burkey, Colby S Shemesh, Thazha P Prakash, Punit P Seth, Eric E Swayze, Richard S Geary, Yanfeng Wang, Scott Henry Molecular Therapy - Nucleic Acids Volume 5, (January 2016) DOI: /mtna Copyright © 2016 Official journal of the American Society of Gene & Cell Therapy Terms and Conditions
