Molecular evidence demonstrated that human lactoferrin gene had been integrated into the genome of transgenic carrot plants 对转基因植株进行分子检测,证实了外源基因已整合到胡萝卜基因组中。

The reason for this reduction in iron absorption is that the breastmilk proteins , lactoferrin and transferrin , can become saturated by the excess iron 铁的吸收率减少的原因在于母乳中的蛋白质:乳铁蛋白(乳铁传递蛋白)和铁传递蛋白,会被过量的铁饱和。

Transformation of human lactoferrin gene to carrot may elevate the transgenic carrot nutritional and functional value , if the transgene expresses correctly , since lactoferrin is a multifunctional protein 把人乳铁蛋白基因转入富含类胡萝卜素和植物纤维的胡萝卜,让它合成具有生物活性的人乳铁蛋白,相当于在营养丰富的胡萝卜中添加新的营养保健因子。

3 . transformation of lactoferrin gene to carrot and its molecular evidence human lactoferrin gene was incorporated into pbi121 plasmid at xba i and sac i sites instead of gus gene , and then transferred into carrot using agrobacterium - mediated strategy 3 .人乳铁蛋白基因在胡萝卜中的转化及分子检测以pbll21为中间载体,把人乳铁蛋白基因替换到gus位置上,构建成表达载体pbihlf 。

The cultured cell suspensions tested by western - blotting showed that transfected cells could express the exogenous gene and secrete human lactoferrin protein , with mw of 34 kd . the highest amount detected with elisa reached 65mg / l medium / 105 cells . the recombinant hlf protein has the effect of inhibiting e . coli proliferation , whose activity is 1 . 4 - 1 . 8 times higher than the commercially available hlf 诱导后,培养液上清通过western - blotting分析证明,转染细胞表达并分泌出人乳铁蛋白,分子量为34kd ; elisa检测重组蛋白最高表达量为65mg l培养基10 ~ 5细胞;抗菌实验表明,所获得的重组人乳铁蛋白具有抑制大肠杆菌生长的作用,而且比人乳铁蛋白标准品作用更强。
