Study on construction of hepatocyte growth factor expression vector system and stable expression in rat bone marrow stem cells with 基因的逆轉(zhuǎn)錄表達(dá)載體及體外感染骨髓間充質(zhì)干細(xì)胞的研究
Usin g a silkworm baculovirus expression vector system ( bevs ) , a large amount of appa phytase was obtained ( up to 7710 per ml hemolymph ) 感染五齡家蠶后appa植酸酶的表達(dá)量達(dá)到平均每毫升血淋巴7710u 。
In this study , with adeasy vector system , the recombinant adenovirus containing huctla4 - ig gene was constructed 目前,關(guān)于基因轉(zhuǎn)移huctla4 - ig誘導(dǎo)同種異體移植物耐受的研究,國(guó)外僅有少數(shù)實(shí)驗(yàn)室開(kāi)展,國(guó)內(nèi)未見(jiàn)報(bào)道。
Pgem - t vector system , jm109 competent cells , reverse transcription kit and in vitro translation kit were purchased from promega company Pgem一t載體,感受態(tài)細(xì)菌jm109 ,反轉(zhuǎn)錄試劑盒和體外翻譯試劑盒均購(gòu)自promega公司。
For desired gene replacement , hyg / cml and str / spc gene cassettes were also incorporated into the new vector system . it is expected that hygwould be integ 為了驗(yàn)證新型yac載體系統(tǒng)的功能,我們將phz621 ~ phz622進(jìn)行了適當(dāng)?shù)馗脑?,?gòu)建了質(zhì)粒phz625 。
For mass production of egf , bombyx mori baculovirus expression vector system ( bevs ) was adopted in this experiment to express recombinant egf 為大量獲得egf ,本研究利用家蠶桿狀病毒表達(dá)系統(tǒng),以家蠶作為生物反應(yīng)器,在家蠶細(xì)胞和幼蟲(chóng)中表達(dá)人表皮生長(zhǎng)因子。
In the same time , comparison principle establishs the relation between complicated vector systems and simple scalar systems , which makes it possible to get stronger results with fewer conditions 同時(shí),比較原理可以建立復(fù)雜的向量系統(tǒng)與簡(jiǎn)單純量系統(tǒng)之間的關(guān)系,這使得在較少條件下得到較強(qiáng)結(jié)果成為可能
Phz621 - phz622 , the new gene replacement vector system , had been constructed through the insertion of the 1 . 0kb and 1 . 4kb flanking sequences of hau3r gene from wild - type s . lividans in the same natural orientation 預(yù)期在攜帶有大插入片段的基因置換yac分子進(jìn)入野生型變鉛青鏈霉菌后, yac分子將通過(guò)1 . 4kb或1
( 一 ) foreign genes can be expressed effectively at low cost in silkworm - bmnpv expression vector system ( silkworm bioreactor ) , which is widely noticed in the world . numerous useful proteins have been expressed and the expression levels were higher in silkworm - bmnpv expression vector than that of others systems (一)家蠶bmnpv表達(dá)載體系統(tǒng)(家蠶生物反應(yīng)器)作為外源蛋白的低成本高效生產(chǎn)體系日益受到國(guó)內(nèi)外的關(guān)注,數(shù)百種有用蛋白已在家蠶中獲得成功的表達(dá)。
