Web1 gen 1999 · Infection with SV40 or transfection with vectors carrying the gene coding for the SV40 large T-antigen can lead to immortalization of primary cells and can induce tumor formation in animals ( 5–7 ). Therefore, such vectors are only partially useful for gene transfer into mammalian cells. http://www.kenkyuu2.net/cgi-biotech/biotechforum.cgi?mode=view;Code=4299 irps exam

The 293T cells are engineered to express the SV40 large T-antigen, a multifunctional proteins that can initiate DNA replication from plasmids containing the ori … WebTaken together, these results indicate that insertion of the SV40-ori promoter in a lentiviral vector contributes to long-term expression by promoting episomal replication when TAg is provided in trans. Lentiviral episomal vectors may serve as specific tools for therapeutic approaches to diseases, particularly those associated with episomal replication of DNA … Web逆にSV40 oriを含んだプラスミドが、COS細胞や293T細胞の中で増幅されるような場合には、コピー数が上がりすぎて最後は細胞が死んでしまいます。 いずれにしても安定に導入遺伝子が発現し続けるためには、ゲノムに組み込まれる必要があるということです。 irps radiation
