Based on NIH-3T3 cells. Retroviral vectors were produced in 293T cells by cotransfection of gag-polgpt, HCMV-G, and a genomic RNA-encoding vector. The number of neoR cfu/mL was determined after 2-week selection of NIH-3T3 cells in G418-containing medium (500 μg/mL). Average values reported refer to n = 6-8 independent titration experiments.
