摘要
利用农杆菌介导的方法,将葡激酶(Staphylokinase,SAK)基因导入番茄中。经PCR、Southern杂交和Northern杂交检测,葡激酶基因已整合到再生番茄植株基因组中,共获得8个转基因株系。经ELISA检测,转基因番茄的果实和叶片均能表达SAK蛋白,SAK蛋白在果实和叶片可溶性蛋白中的比例最高分别为3.42%和2.47%。转基因番茄中的SAK蛋白具有一定的溶栓活性,溶栓比活力为3 866 AU·mg-1。
In this study, we introduced SAK into tomato via Agrobacterium tumefaciens-mediated transformation. Staphylokinase gene had been integrated into the genome of regenerated tomato plants by PCR, Southern crossbreeding and Northern crossbreeding, 8 transgenic tomato lines were indentified. Through ELISA test, transgenic tomato fruits and leaves could show SAK protein. The SAK protein content in transgenic tomato fruits and leaves reached levels of 3.42% and 2.47%. SAK protein possessed a certain of fibrinolytic activity in transgenic tomato, fibrinolytic activity was 3 866 AU/mg.
