In this study, a new horizontal microinjection system has been established to solve these problems. Because the average time per pronuclear embryo by microinjection has been significantly shortened with the horizontal system, the cleavage rate and 16-cell rate of those microinjected embryos increased markedly.

To pronuclear formation rate after oocyte in vitro maturation 18 hours and parthenogenticactivation, oocytes derived from SM is significantly higher than oocytes from PM,oocytes derived from IM is significantly lower that of oocytes detrived from PM and SM.

对于孤雌刺激反应而言，无论是何种类型的卵母细胞成熟18小时后，自发成熟卵母细胞激活后形成原核的比率高于被动成熟的卵母细胞，诱导成熟的卵母细胞的原核形成率显著低于自发和／或被动成熟的卵母细胞。

Methods: Total RNA was extracted from esophageal carcinoma tissue, the primer containing special enzyme was designed, NY-ESO-1 fragment was amplified by RT-PCR, and then was cloned into the expression vector pET-15b by LP Recco PCR Cloning. The recombinants plasmid pET-15b-NY-ESO-1 were identified by restriction endonucleases digest analysis and sequence analysis.

Compared genes up- and down-stream IL-21 between Tetraodon nigroviridi, Fugu rubripes and human, a high degree of conservation of synteny was found.

将TnIL-21 CDS序列克隆到原核表达载体pET32b中，成功地构建重组载体TnIL21-pET32b，并建立其原核表达体系，成功诱导目的蛋白的大量表达。

The recombinant protein were purled from prokaryotic bacteria hadactivity of binding to IBV in ELISA and Western blotting test, which could be blocked byantiserum against gAPN.

将原核表达的gAPN蛋白进行的ELISA及Westem blotting试验证实原核表达的gAPN蛋白在体外可以与IBV结合，而且这种结合可以被针对gAPN的抗体阻断。

In a word, we extracted first cotyledon of buckwheat total RNA, by method of RT-PCR and 3RACE, get the C terminal cDNA sequence of PI from Ukraine buckwheat, and do some bioinformatics analyse on this cDNA sequence of PI from buckwheat, such as gene characteristics, expression mode. All of this will be help for the forward research on functional protein and high performance of procaryon expression or eukaryon expression.
