Lentiviral Vector Purification Using Nanofiber Ion-Exchange Chromatography [PDF]

open access: yesMolecular Therapy: Methods & Clinical Development, 2019
Lentiviral vectors (LVs) are used in cell and gene therapies due to their ability to transduce both dividing and non-dividing cells while carrying a relatively large genetic payload and providing long-term gene expression via gene integration.
