PGKGFP virus was produced with wild type ABCB4, mutant ABCB4 or with ABCC1. The amount of p24 per ml and the viral titers were determined. Co expression of ABCB4 during viral production significantly reduces viral vector infectivity.
aThe data for TU/ml and p24/ml are presented as a percentage, with the co-transfection of empty vector during the production of lentiviral vectors given an arbitrary value of 100%. Significant difference p < 0.01* or p < 0.001** compared to ABCB4 co-expression. Mean values are presented ± SD.
