    • The present application disclosed a method for preparing a sterile transgenic fish, comprising constructing antisense RNA expression vector of salmon-type gonadotropin-releasing hormone, introducing the recombinant DNA fragment into carp oosperm by microinjection, and screening the sterile transgenic fish by Polymerase Chain Reaction and radioimmunoassay, wherein the expression vector comprising a promoter of carp beta actin (β-actin) gene, a complementary DNA fragment of antisense salmon-type gonadotropin-releasing hormone (sGnRH) gene from carp with 323 bp as a target gene comprising sGnRH decapeptide, the coding region of gonadotropin-releasing hormone associated peptide and 3′ non-coding sequence, and 3′ flanking sequence of grass carp growth hormone gene as a stop sequence. The method of the present invention is easy and convenient for operation which provides a basis for providing a technical platform of general applicability for solving the hereditary and ecological safety problems of transgenic fishes.
    • 本申请公开了一种制备无菌转基因鱼的方法,包括构建鲑鱼型促性腺激素释放激素的反义RNA表达载体,通过显微注射将重组DNA片段引入鲤鱼胚乳,并通过聚合酶链式反应筛选无菌转基因鱼, 放射免疫测定法,其中包含鲤鱼β肌动蛋白(β-肌动蛋白)基因启动子的表达载体,具有323bp作为靶基因的来自鲤鱼的反义鲑鱼型促性腺激素释放激素(sGnRH)基因的互补DNA片段,其包含sGnRH十肽, 促性腺激素释放激素相关肽和3'非编码序列的编码区和草鱼生长激素基因的3'侧翼序列作为停止序列。 本发明的方法操作简单方便,为提供解决转基因鱼遗传和生态安全问题的通用技术平台提供依据。
