Overview

ArciTect™ tracrRNA is a trans-activating CRISPR RNA (crRNA), one of two RNA components required to make a guide RNA (gRNA) for CRISPR-Cas9 genome editing. ArciTect™ tracrRNA contains a complementary sequence to the linker sequence in ArciTect™ crRNA, allowing fast and efficient gRNA duplex formation. ArciTect™ tracrRNA is recognized by all ArciTect™ Cas9 nucleases and is essential for ribonucleoprotein (RNP) complex formation. It contains 2'-O-methyl and phosphorothioate modifications at the first two 5' and 3' terminal residues for optimal stability and editing efficiency.The ArciTect™ tracrRNA Kit includes tracrRNA as well asArciTect™ Annealing Buffer (5X), which is required for forming a gRNA duplex between ArciTect™ tracrRNA and ArciTect™ crRNA. ArciTect™ crRNA is available by custom order for user-specified target sequences, in 2 nmol (Catalog #76010), 10 nmol (Catalog #76011), and 20 nmol (Catalog #76012) sizes. ArciTect™ Cas9 Nuclease is also available separately (Catalog #76001).
