摘    要:应用非同位素标记染色体原位杂交技术,对9头不同世代的转OMT-PGH帮6头原代转hDAF基因猪外源基因整合位点的分布及其遗传规律进行了研究。结果表明,4头原代转OMT-PGH基因猪外源基因分别整合在第7,13,2和8号染色体上,6头原代转hDAF基因猪外源基因分别整合在第13,6,11,2,7和7号染色体上,证实了用原核注射法转基因猪外源基因的整合是“随机”的,来自同一亲本,不同世代的5头转OMT-PGH基因猪,其外源基因均存在于第13号染色体上,与共同祖先原代转基因猪的整合位点相一致,表明转基因猪外源基因可以传递给后代,且整合位点的遗传是相对稳定的。

关 键 词:原核注射法 外源基因 分布 遗传规律 原位杂交 染色体 整合位点 转基因猪

Abstract:Using non radio label chromosome situs blot technique,the distribution and heredity regulation of sites combined foreign gene in 6 finders with hDAF gene and 9 transgenic pigs from different generations with OMT PGH gene were investigated.The results indicated the OMT PGH gene located in chromosome 7,13,2 and 8 of 4 finder transgenic pigs.The hDAF gene sited in chromosome 13,6,11,2,7 and 7.This means that the foreign gene integration on chromosome is random when transgenic pig is produced by microinjection procedure.Five OMT PGH transgenic pigs from different generation shared the same integration site in chromosome 13 with their mutual ancester.This shows that the foreign gene may be heridable and its sits is stable.
Keywords:situs blot  chromosome  integrated sit  transgenic pig
