The optimized DMEM, by means of a statistical optimization approach, was supplemented with some cell growth factors, such as insulin, transfferin etc.

再采用统计学正交分析方法，在初步优化的DMEM培养基中添加胰岛素、转铁蛋白等促细胞生长因子，建立了一种适于CHO C2 8细胞持续用无血清培养基———CHO C2 8 SFM。

In present papers,38 cases of breast carcinoma and 30 cases of breast adenosis were examimated by immunohistochemical method.

采用抗人胎盘酸性同功铁蛋白单克隆抗体和免疫组化方法对38例乳腺癌和30例乳腺腺病组织进行了检测。

Then the caprine fetal fibroblast cells were transfected with p6.5hLF-EGFP by LipofectamineTM-2000 and selected by G418 for 3 to 4 weeks. The G418 resistant transfectants were identified by PCR and EGFP detection. The results indicated that the transgene was stably integrated into the open region of the chromatin of G418 resistant fibroblast cells.

脂质体介导法转染山羊胎儿成纤维细胞，G418抗性筛选3-4周后，经PCR扩增和报告基因EGFP表达检测，得到稳定整合外源基因的转基因供体细胞系，为制备高效表达人乳铁蛋白的转基因山羊乳腺生物反应器提高可靠的核移植供体细胞。

Ferritin from the liver of a salt water fish, Dasyatis akajei, herein called DALF, was isolated and purified by thermal denaturation, ammonium sulphate fractionation and ammonium reverse extraction, Sephacryl S-300 gel filtration and DEAE- cellulose anion exchange chromatography.

通过热变性处理、硫酸铵分级沉淀、排阻层析和离子交换层析等技术，分离纯化了魟鱼肝铁蛋白Liver ferritin of Dasyatis akaiei。

A suitable expression system is required for heterologous expression of human lactoferrin.

目前常用的表达系统中，动物乳腺是人乳铁蛋白基因表达较为合适的器官。

Results There existed decreasing learning and memory function, increasing MAO-B activity from the cortex, hippocampus, and strium, elevating brain iron and aluminum levels with diminishing ferritin level, and karyopyknosis as well as neuron loss of hippocampus in the model mice.

结果 模型组小鼠学习记忆能力明显下降，大脑皮层、海马和纹状体MAO-B活力增加，脑铁水平明显升高，线粒体铁蛋白水平下降，而海马CA1区神经元核固缩和神经细胞丢失。

The main component include promoter sequence (5' flank control rigon of goat P - lacto globulin gene of goat),foreign gene,Marker gene and genome of defective retrovirus.

其中主要构建元件包括：启动子序列(山羊β-乳球蛋白基因5'端调控区)；外源基因(人乳铁蛋白基因cDNA)；标记基因；缺陷型逆转录病毒基因组。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.
