Targeted transduction of CD20-positive human primary B cells. (a) Fresh unfractionated human PBMCs (1 × 10⁶) were spin-transduced twice with indicated vectors (FUGW/αCD20+FM, 2.5 × 10⁶ TU, or FUGW/VSVG, 25 × 10⁶ TU). 48 hours later, cells were collected and analyzed by FACS (b) iMFI on fresh unfractionated human PBMCs transduced by the indicated viral vectors (FUGW/αCD20+FM, and FUGW/VSVG).
