Abstract:
Retrovirus (RV) is the most widely used vector for gene transfer, but its efficiency is very low for human cells. A Flow-through Transduction System made in General Hospital of PLA was used to deliver interleukin-12 RV vector into human leukemia cell line K562. Compared with static procedure, the efficiency could be significantly improved,and detected by clony forming units (CFU) for NeoR gene in semisolid culture medium with G418 ( 83.1%?3.9% vs 9.2%?2.3%, P0.05), while statically transducted cells without G418 selection could express very low IL-12 (0.1?0.024ng/ml,P
