摘    要:将包括α-sl酪蛋白基因的启动子、LAtPA小基因、α-sl酪蛋白基因下游调控序列的融合基因经显微注射至小鼠的受精卵中,获得了5只转基因阳性鼠,其中1只转基因阳性雌鼠乳清中LAtPA的含量为0.18αg/ml,说明构建的LAtPA小基因能够正确表达出有生物活性的LAtPA, 在酪蛋白基因调控序列的指导下在小鼠乳汁中表达。

关 键 词:组织型纤溶酶原激活剂 酪蛋白基因 转基因小鼠 乳腺生物反应器 tPA

Abstract:The fusion gene containing the promoter of casein gene, LAtPA minigene and 3' flanking sequences of casein gene was introduced into the fertilized eggs of mice by microinjection. Five positive transgenic mice were obtained. The concentration of LAtPA in the milk of one female transgenic mouse is 0.18μg/ml. This result showed that the LAtPA minigene could correctly express the bioactive LAtPA in the milk of the transgenic mouse under the control of the regulatory elements of the casein gene.
