GENPower? NLS-Cas12a Nuclease (MALS verified)
優(yōu)勢特色(Features)
With two NLS, which leads to transport to the nucleus efficiently.
High cleavage activity
產(chǎn)品描述(Product Details)
GENPower? NLS-Cas12a Nuclease is a recombinant Lachnospiraceae bacterium Cas12 protein purified from Escherichia coli for CRISPR-based genome editing. The introduction of nuclear localization signals (NLS) can help Cas12 enter the nucleus, increasing the chance of genomic DNA cleavage.

Cas12a分子背景
來自Lachnospiraceae細(xì)菌的簇狀規(guī)則間隔短回文重復(fù)序列(CRISPR)相關(guān)內(nèi)切酶Cas12a,也稱為Cpf1,是一種1200-1500個(gè)氨基酸長的單體蛋白,屬于CRISPR/Cas系統(tǒng),這是一種原核生物的適應(yīng)性免疫系統(tǒng),現(xiàn)已成為基因組編輯的強(qiáng)大工具。CRISPR/Cas12a屬于CRISPR/Cass系統(tǒng)的II類(5型),由單個(gè)亞基效應(yīng)器定義。Cas12a最近成為Cas9的替代品,因?yàn)樗哂歇?dú)特的特征,如靶向富T基序的能力、不需要反式激活crRNA、誘導(dǎo)交錯(cuò)雙鏈斷裂以及RNA加工和DNA核酸酶活性的潛力。此外,Cas12a能夠?qū)⒔Y(jié)構(gòu)更復(fù)雜的CRISPR/RNA(crRNA)前分子加工成成熟的crRNA,這使得將成熟或前crRNA用于基因組編輯成為可能。所有這些特征使CRISPR/Cas12a系統(tǒng)成為一種有價(jià)值的基因組工程工具。CRISPR-Cas12a已成功用于編輯許多哺乳動(dòng)物細(xì)胞和植物的基因組。
