重組蛋白
重組蛋白質(zhì)是分析生物相互作用的有用工具。在研究實驗室中使用了大量的重組蛋白質(zhì),包括商業(yè)蛋白質(zhì)和在特定研究項目中生成的蛋白質(zhì)。它們在許多應(yīng)用中發(fā)揮著關(guān)鍵作用。
如果您正在尋找具有優(yōu)良質(zhì)量(驗證的生物活性,較低的內(nèi)毒素水平和高純度)的重組蛋白質(zhì)來支持您的研究,您來對地方了。
經(jīng)過16多年的發(fā)展,華美生物已經(jīng)建立了從原核到真核的五大系統(tǒng),用于表達(dá)重組蛋白質(zhì)。我們擁有一系列蛋白質(zhì)表達(dá)和純化技術(shù),包括基于桿狀病毒外膜蛋白(OMP)的蛋白質(zhì)表達(dá)技術(shù),以及膜蛋白表達(dá)技術(shù)等。
產(chǎn)品特點(diǎn)
- 超過10,000種重組蛋白覆蓋大多數(shù)基因/靶點(diǎn);
- 5種表達(dá)系統(tǒng),包括大腸桿菌(E.coli)、酵母、桿狀病毒感染的昆蟲細(xì)胞、哺乳動物細(xì)胞和體外大腸桿菌。而體外大腸桿菌表達(dá)系統(tǒng)是華美生物的獨(dú)特表達(dá)系統(tǒng)。與傳統(tǒng)蛋白表達(dá)系統(tǒng)相比,體外大腸桿菌省略了許多過程,如質(zhì)粒轉(zhuǎn)化、細(xì)胞培養(yǎng)、收集、破碎和離心等,大大提高了工作效率。
- 多種標(biāo)簽,包括His、GST、Flag、MBP等。

有用資源
什么是重組蛋白?
重組蛋白是一種可操縱的蛋白質(zhì)形式,可以通過多種方式產(chǎn)生大量蛋白質(zhì)、修改基因序列和制造有用的商業(yè)產(chǎn)品。重組蛋白的技術(shù)資源在重組蛋白的開發(fā)過程中,除了表達(dá)系統(tǒng)之外,還面臨著一系列令人困惑的選擇,如表達(dá)載體的選擇、表達(dá)蛋白的長度(全長或部分)、是否帶標(biāo)簽等。在生產(chǎn)重組蛋白時,你必須做出很多決定。如果你選擇的明智,你將獲得高質(zhì)量的重組蛋白,后續(xù)的實驗更有可能成功。但是如果你做了錯誤的決定,你可能得不到你所需要的重組蛋白或者重組蛋白的質(zhì)量和純度不符合要求。在這里,來自CUSABIO的蛋白表達(dá)工程師根據(jù)他們開發(fā)重組蛋白的經(jīng)驗總結(jié)出了幾個有用的提示,可以幫助你做出明智的決策。
第一條:重組蛋白的生產(chǎn),在這篇文章中,我們旨在闡明重組蛋白的定義以及如何生產(chǎn)重組蛋白。
第二條:如何選擇合適的表達(dá)載體?
表達(dá)載體是一種DNA分子,它攜帶特定的基因進(jìn)入宿主細(xì)胞,并利用細(xì)胞的蛋白質(zhì)合成機(jī)制來產(chǎn)生由該基因編碼的蛋白質(zhì)。表達(dá)載體可使外源基因在宿主細(xì)胞中高效表達(dá),經(jīng)過多年的發(fā)展,表達(dá)載體已成為一種成熟而受歡迎的生物技術(shù)。在重組蛋白生產(chǎn)過程中是一種基本成分。正如標(biāo)題所示,本文主要總結(jié)了幾個有用的技巧來選擇合適的表達(dá)載體。
根據(jù)重組蛋白的不同應(yīng)用,對其生物活性有不同的要求。但是我們?nèi)绾未_保蛋白質(zhì)的產(chǎn)生具有生物活性呢?本文將圍繞這個主題,并提供一些解決方案。除了以上文章,我們還收集了一些重組蛋白的常見問題。您可以單擊以下鏈接查看。http://m.cstxtech.com/technology-91.html。此外,我們還為我們的客戶提供重組蛋白表達(dá)服務(wù),您可以點(diǎn)擊這里獲取更多信息。注:如果您對CUSABIO的蛋白質(zhì)有任何疑問,涉及到蛋白質(zhì)的價格、交貨、質(zhì)量等,您可以點(diǎn)擊橙色按鈕為我們在線留言。
