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）
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.
应用说明（Application）
Developed as a variety of genome editing tools, such as transcription regulation, gene recombination, and base editing.
