| [sequence analysis of integration sites of reticuloendotheliosis virus ltr in fowlpox vaccine virus genomes]. | by use of genomic dna prepared from 5 fowlpox virus (fpv) vaccines made in china (from shandong, beijing, liaoning, zhejing and shanghai respectively) as the templates, reticuloendotheliosis virus (rev) ltr was amplified in pcr with a pair of primers synthesized according to the sequences flanking the integrated rev-5'ltr in fpv genomes published in us and australia. sequence analysis indicated that the rev-5'ltr integration sites in genomes of all 5 chinese pfv vaccine products were identical t ... | 2006 | 17037075 |
