GENPower™ NLS-Cas12a Nuclease (MALS verified)
优势特色(Features)
With two NLS, which leads to transport to the nucleus efficiently.
High cleavage activity
产品描述(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
来自Lachnospiraceae细菌的簇状规则间隔短回文重复序列(CRISPR)相关内切酶Cas12a,也称为Cpf1,是一种1200-1500个氨基酸长的单体蛋白,属于CRISPR/Cas系统,这是一种原核生物的适应性免疫系统,现已成为基因组编辑的强大工具。CRISPR/Cas12a属于CRISPR/Cass系统的II类(5型),由单个亚基效应器定义。Cas12a最近成为Cas9的替代品,因为它具有独特的特征,如靶向富T基序的能力、不需要反式激活crRNA、诱导交错双链断裂以及RNA加工和DNA核酸酶活性的潜力。此外,Cas12a能够将结构更复杂的CRISPR/RNA(crRNA)前分子加工成成熟的crRNA,这使得将成熟或前crRNA用于基因组编辑成为可能。所有这些特征使CRISPR/Cas12a系统成为一种有价值的基因组工程工具。CRISPR-Cas12a已成功用于编辑许多哺乳动物细胞和植物的基因组。
