TriAltus' highly pure, tag-free Cas12b is used for genome editing with CRISPR technology and CRISPR-mediated in vitro applications. Recombinant Alicyclobacillus acidiphilus Cas12b (AapCas12b) protein is expressed in E. coli and features two C-terminal nuclear localization signals (NLS). AapCas12b protein combines with guide RNA (gRNA) to form a stable ribonucleoprotein (RNP) complex that enables the inactive nuclease to be guided to the specific double stranded DNA (dsDNA) site. Once guided to the specific cleavage site, AapCas12b becomes activated to specifically and precisely cleave the dsDNA and to indiscriminately trans-cleave single stranded DNA (ssDNA) nearby.

Figure 1. CLīM-purified AapCas12b’s trans-cleavage nuclease activity compared to commercially obtained (“C.O.”) AapCas12b. Upon hybridization of the Cas12b/sgRNA RNP to the target, dsDNA activator, Cas12b becomes active to cleave the activator as well as to trans-cleave nearby nonspecific ssDNA. Activated Cas12b cleaves dual-labeled fluorophore and quencher (FQ)-ssDNA Reporter, which releases the fluorophore to emit a fluorescent signal. Raw RFU values from each reaction were corrected by subtracting the background fluorescence value of the appropriate “no activator” control. The average of the corrected RFU values and SEM are reported. Each condition was performed in technical triplicates.
AapCas12b obtained from a commercial source or CLīM-purified AapCas12b was combined with annealed sgRNA for 10 minutes at room temperature to create functional AapCas12b RNP complexes. Reaction buffer was used in the place of protein for the “No Cas12b” control. A mixture of target dsDNA activator and a nonspecific FQ-ssDNA reporter was added to the designated RNP reactions. The reaction proceeded for 30 minutes at 37°C, equilibrated to room temperature for 10 minutes, and the fluorescence was measured. The reaction systems comprised the following: 0 or 40nM AapCas12b, 44nM sgRNA, 0 or 1 nM Activator, 100 nM FQ-Reporter and 1x NEBuffer r2.1 (New England Biolabs).
