RT - Journal Article T1 - Designing E1 Deleted Adenoviral Vector by Homologous Recombination JF - انستیتو-پاستور-ایران YR - 2007 JO - انستیتو-پاستور-ایران VO - 11 IS - 3 UR - http://ibj.pasteur.ac.ir/article-1-144-en.html SP - 199 EP - 202 K1 - Adenoviral vectors (AdV) K1 - Adenovirus K1 - Homologous recombination AB - Adenoviruses are used extensively to deliver genes into mammalian cells, particularly where there is a requirement for high-level expression of transgene products in cultured cells, or for use as recombinant viral vaccines or in gene therapy. In spite of their usefulness, the construction of adenoviral vectors (AdV) is a cumbersome and lengthy process that is not readily amenable to the generation of large collection of clones. Methods: In this project, to delete E1 gene in adenovirus, an adenoviral plasmid containing lateral sites of E1 region of adenovirus was made and recombination in the 293A cells between the homologous region of this linearized plasmid and the adenovirus genome resulted in the formation of the complete adenoviral recombinant. Results: This recombination resulted in loss of E1 region and we constructed a recombinant adenovirus type 5 vector that E1 gene was deleted by homologous recombination. Conclusion: Homologous recombination is more easy and fast technique in the production of AdV. LA eng UL http://ibj.pasteur.ac.ir/article-1-144-en.html M3 - ER -
