Passage at 1: 2. The cells can be overgrowth within 3 days. Mouse Embryonic Fibroblast; PA317 NICR495 Negative PA317 PA317 cell PA317 cells derived from TK-NIH/3T3 cells were constructed by co-transfection of the packaging structure DNA (pPAM3) in pBR322 and the herpes simplex virus thymidine kinase gene in pBR322. The introduction of retroviral vectors into these cells by infection or transfection results in the formation of amphotropic vector particles that can infect many mammalian cells. Viral particles generated from the cells have been successfully used to introduce genes into humans. The percentage of PA317 cells capable of packaging retroviral vectors decreases with passage, possibly due to the loss of transferred DNA used to construct this strain of cells. A brief (approximately 5 days) selection in media containing 0.03 mM hypoxanthine, 0.001 mM methotrexate and 0.02 mM thymidine can select the ability of retaining the packaging function. The screened cells should be cultured in HT medium for 4 days to dilute the residual methotrexate.
