Lonza Amaxa 4D-Nucleofector細(xì)胞核轉(zhuǎn)染系統(tǒng)
——哺乳動物真核細(xì)胞高效基因轉(zhuǎn)染
德國進(jìn)口Lonza 4D-Nucleofector細(xì)胞核轉(zhuǎn)染系統(tǒng)(原Amaxa 4D-Nucleofector核轉(zhuǎn)儀),創(chuàng)新性地結(jié)合經(jīng)典電穿孔技術(shù)和細(xì)胞特異性電轉(zhuǎn)染液,實(shí)現(xiàn)了DNA、RNA(如crRNA、tracrRNA、gRNA、sgRNA)、RNP核糖核蛋白復(fù)合體、蛋白質(zhì)(如Cas9核酸酶、切口酶、dCas9蛋白、Cas12a/Cpf1核酸酶)、小分子物質(zhì)高效轉(zhuǎn)染各類哺乳動物貼壁細(xì)胞、懸浮細(xì)胞、外泌體exosome等。
新款Lonza 4D核轉(zhuǎn)儀由用于小規(guī)模轉(zhuǎn)染的X模塊(4D-Nucleofector X Unit)、貼壁細(xì)胞不經(jīng)消化進(jìn)行原位轉(zhuǎn)染的Y模塊(4D-Nucleofector Y Unit)、單一細(xì)胞大規(guī)模流式轉(zhuǎn)染的LV模塊(4D-Nucleofector LV Unit)、高通量篩選的96孔模塊(原96-well Shuttle Device)組成。 點(diǎn)擊查看:Lonza Nucleofector 2B Device 單孔核轉(zhuǎn)儀2B型號
Lonza 4D-Nucleofector技術(shù)不依賴于細(xì)胞有絲分|裂,不受細(xì)胞增殖的影響,可直接將外源基因?qū)爰?xì)胞核中,即使是未分|裂的原代細(xì)胞(如靜止的T淋巴細(xì)胞或神經(jīng)元),也可以快速表達(dá)。
Lonza 4D-Nucleofector對質(zhì)粒DNA轉(zhuǎn)染效率高達(dá)90%,寡核苷酸(如siRNA)轉(zhuǎn)染效率高達(dá)99%,面世20年來,已成功轉(zhuǎn)染>1200種細(xì)胞系、>130種原代細(xì)胞,并在干細(xì)胞、免疫細(xì)胞、神經(jīng)細(xì)胞等各類較難轉(zhuǎn)染的細(xì)胞、以及外泌體電穿孔裝載藥物中獲得了優(yōu)秀的效果。
由于同種細(xì)胞系或原代細(xì)胞使用相同的轉(zhuǎn)染條件(轉(zhuǎn)染程序和轉(zhuǎn)染試劑盒),Lonza 4D-Nucleofector可實(shí)現(xiàn)多種外源物質(zhì)共轉(zhuǎn)染,例如CRISPR-Cas9基因編輯時共轉(zhuǎn)染2種sgRNA等。

4D-Nucleofector細(xì)胞核轉(zhuǎn)染方法特點(diǎn)
1.針對每種細(xì)胞優(yōu)化的電脈沖參數(shù),可將底物導(dǎo)入細(xì)胞質(zhì)甚至是細(xì)胞核;
2.特殊配方的電轉(zhuǎn)染液,同時提供高轉(zhuǎn)染效率和細(xì)胞保護(hù),提高細(xì)胞轉(zhuǎn)染后存活率;
3.全球共享數(shù)據(jù)庫,專業(yè)指導(dǎo),從細(xì)胞來源、傳代、培養(yǎng)條件、培養(yǎng)基、轉(zhuǎn)染程序選擇和操作技巧、到轉(zhuǎn)染后培養(yǎng)技巧,已形成成熟的實(shí)驗(yàn)方案。
4D-Nucleofector核轉(zhuǎn)染系統(tǒng)為基因治療研究、免疫治療研究、干細(xì)胞研究等提供了方便的工具。相比電穿孔在內(nèi)的其他非病毒轉(zhuǎn)染技術(shù),更具優(yōu)勢:
-采用高分子聚合物電極,避免傳統(tǒng)鋁電極的離子毒害,維持細(xì)胞生理狀態(tài),提高存活率。
-轉(zhuǎn)染后可快速觀察實(shí)驗(yàn)結(jié)果,例如轉(zhuǎn)染GFP后最快2小時可觀察到蛋白。
-無需自己優(yōu)化條件,擁有超過759種細(xì)胞類型的現(xiàn)成程序,可直接使用,全球共享數(shù)據(jù)庫,超過1500條轉(zhuǎn)染數(shù)據(jù)可供參考,并持續(xù)更新。
-可轉(zhuǎn)染包括DNA、mRNA、miRNA、siRNA、RNP、肽、蛋白質(zhì)、小分子化合物在內(nèi)的多種底物。
-可用于難以轉(zhuǎn)染的原代細(xì)胞、干細(xì)胞、神經(jīng)元、細(xì)胞系,以及外泌體
-可不用消化細(xì)胞,進(jìn)行貼壁細(xì)胞的原位轉(zhuǎn)染。
-靈活的轉(zhuǎn)染規(guī)?s放,可在低、中、高通量中輕松轉(zhuǎn)移,實(shí)現(xiàn)2×10^4至1×10^9個細(xì)胞數(shù)量的輕松擴(kuò)展。
-全球發(fā)表文章超過14,000篇。
最近,Lonza 4D-Nucleofector核轉(zhuǎn)染系統(tǒng)已廣泛應(yīng)用于通過RNAi、CRISPR-Cas9、CRISPR-Cas12a進(jìn)行的基因敲除研究、以及iPS誘導(dǎo)多能干細(xì)胞、CAR-NK、CAR-T、外泌體藥物遞送的研究中,在包括功能和結(jié)構(gòu)基因組學(xué)、藥物發(fā)現(xiàn)以及基因和細(xì)胞療法的研究中大放異彩。
4D核轉(zhuǎn)儀結(jié)構(gòu)和功能應(yīng)用:
4D-Nucleofector細(xì)胞核轉(zhuǎn)染系統(tǒng)采用模塊化設(shè)計,可根據(jù)研究者的需求,自行組合數(shù)個模塊形成一套完整系統(tǒng)。
1、C模塊:4D-Nucleofector系統(tǒng)的控制單元,內(nèi)置轉(zhuǎn)染程序,將不同的功能單元(模塊)整合為一個系統(tǒng),以運(yùn)行不同的應(yīng)用程序。
2、X模塊:用于懸浮細(xì)胞、或貼壁細(xì)胞消化后的小規(guī)模轉(zhuǎn)染,轉(zhuǎn)染細(xì)胞數(shù)量2×10^4至2×10^7?赏瑫r轉(zhuǎn)染2個100μL電轉(zhuǎn)杯、1個16孔電轉(zhuǎn)板條(每孔20μL),每個電轉(zhuǎn)杯、每個孔可獨(dú)立設(shè)置程序。另外在使用96孔模塊時,也需要X模塊。
3、Y模塊:用于貼壁細(xì)胞不經(jīng)消化的原位轉(zhuǎn)染,可同時轉(zhuǎn)染1個24孔電轉(zhuǎn)板條(每孔350μL),每個孔可獨(dú)立設(shè)置程序。
4、LV模塊:用于同一種懸浮細(xì)胞、或同一種貼壁細(xì)胞消化后的大規(guī)模轉(zhuǎn)染,轉(zhuǎn)染細(xì)胞數(shù)量1×10^7至2×10^9?墒褂1mL手動進(jìn)樣電轉(zhuǎn)盤、或20mL連續(xù)進(jìn)樣電轉(zhuǎn)盤。通常使用X模塊小試摸條件,再用LV模塊線性放大轉(zhuǎn)染規(guī)模。
5、96孔模塊:用于同時轉(zhuǎn)染96個樣品的細(xì)胞,轉(zhuǎn)染細(xì)胞數(shù)量2×10^4至1×10^6。每個孔可獨(dú)立設(shè)置程序。必須與X模塊結(jié)合使用。
