ArciTect™ CRISPR-Cas9 Genome Editing System for Cell Biologists
The ArciTect™ product family is a CRISPR-Cas9 genome editing system that uses ribonucleoprotein (RNP) complexes composed of purified Cas9 protein and custom synthetic guide RNA. Compared to previous technologies that utilize plasmid or mRNA-based systems, an RNP-based system enables efficient delivery and expression of CRISPR machinery in difficult-to-manipulate cells, including stem and primary cells. Once inside the cell, the RNP complexes will not induce the cellular immune response and will degrade in a timely manner to reduce off-target effects (Table 1). With validated reagents and protocols, the ArciTect™ system enables you to perform high-efficiency genome editing and generate functional gene-edited cells in your own lab.
Overcome Hurdles in Efficiency
Overcome challenges in efficient delivery and expression of CRISPR machinery using an RNP-based CRISPR-Cas9 system. ArciTect™ enables researchers to perform high-efficiency genome editing in difficult-to-manipulate cell types, including stem and primary cells.
Why Use ArciTect™?
