The departure of the northern kingdom of Israel from the Davidic dynasty is deplored, and the history of the southern kingdom of Judah is told with the intent of reuniting all Palestinian Jews in the purified temple worship at Jerusalem in postexilic times (after 537 BC).

离开英国北部的以色列从Davidic时期是遗憾，和历史上的犹太王国南部是告诉意图团聚所有巴勒斯坦犹太人在纯化寺礼拜在耶路撒冷的postexilic次（后537年）。

The results showed that the most important factors related to the accuracy were the recrystallized potassium persulfate and the sodium hydroxide.

通过试验发现，过硫酸钾、氢氧化钠的纯度是影响测定准确性的最重要因素，其中分析纯AR级的过硫酸钾(K2S2O8)经纯化处理可以降低空白值；消解时间的延长和消解温度增加对提高实验准确性的影响不显著。

Progress in cloning techniques, microbiology and protein purification has been supplying an ever-growing number and quantity of preparatively useful biocatalysts. Initially enzymes were only used to synthesize compounds found in nature.

近年来人们在克隆技术，微生物学以及蛋白纯化方面的研究成果为我们提供了越来越多的生物催化剂，酶最初用于天然产物的合成，而今其在非天然化合物中的应用更引起了生物化学家的广泛关注。

To make the transgenic mice: We purified the gene fraction nestin-hsp68-EGFP and injected it into pronucleus of mouse zygotes to generate the transgenic mice.

1。转基因小鼠的获得：纯化基因片段nestin-hsp68-EGFP，用显微注射方法把基因片段注射到受精卵的雄原核中，获取转基因小鼠。

Pronucleus expression recombinant pMAL-C2X-HBV-X is constructed successfully and with the IPTG induction, the recombinant pMAL-C2X-HBV-X can express the X protein in E. coli JM109, which lays the foundation fur the HBV X protein purification and its biological study.

成功构建了HBV X基因原核表达重组体pMAL-C2X-HBV X；在IPTG的诱导下，该重组体在大肠杆菌中可表达X融合蛋白，为进一步纯化HBV X蛋白和研究其生物学作用奠定了基础。

Hordenine propyl formate and chemical osmosis are the two ways of extracting Glutathione from yeast have been introduced and compared in this review.

介绍了从酵母中分离纯化谷胱甘肽的两种抽提方法：对羟基苯甲酸丙酯法和化学渗透法，并对其进行了对比。

Results (1)Astrocytes and oligodendrocytes in mixed culture appeared better growth and differentiation than the respectively purified neuroglial, especially for the oligodendrocytes.(2) There were many pseudopod process among the astrocytes, which appeared centripetal growth mode.(3) The passaged astrocytes kept good abilities of division and proliferation and completely fused after 1 week of growth, and the purity was over 95%.

结果 (1)混合培养的星形胶质细胞和少突胶质细胞生长分化状况均优于纯化后的生长，以少突胶质细胞表现更为明显；(2)星形胶质细胞呈向心性生长，细胞相邻的接触面有较多的伪足；(3)传代培养的星形胶质细胞保持较强的分裂增殖能力，可在1周左右生长至完全融合，其纯度可达95%以上。

Obtaining relative pure OECs through isolation and culture is the most important.
