Alt-R A.s. Cas12a (Cpf1) nuclease
Alt-R A.s. Cas12a (Cpf1) Nuclease V3 enzyme is a high purity, recombinant Acidaminococcus sp. BV3L6 Cas12a. The enzymes include nuclear localization sequences (NLSs) and C-terminal 6-His tags. The Cas12a enzyme must be combined with a gRNA to produce a functional, target-specific editing complex. For the best editing, combine Alt-R A.s. Cas12a (Cpf1) Nuclease V3 enzyme with optimized Alt-R CRISPR-Cas12a (Cpf1) crRNA in equimolar amounts.
Attention: Unlike S. pyogenes Cas9, which cleaves most NGG PAM sites to some degree, some of the tested TTTV sites show no cleavage by A.s. Cas12a nuclease. We recommend using positive control crRNAs to establish that your cells can be edited by Cas12a. In addition, we suggest testing 3 or more crRNAs per target gene.
