EnGen® Lba Cas12a (Cpf1)
EnGen Lba Cas12a (Cpf1) is a programmable DNA endonuclease guided by a single guide RNA (gRNA). Targeting requires a gRNA complementary to the target site as well as a 5′ TTTV protospacer adjacent motif (PAM) on the DNA strand opposite the target sequence. Cleavage by EnGen Lba Cas12a (Cpf1) occurs ~17 bases 3′ of the PAM and leaves 5′ overhanging ends.
- T-rich TTTV PAM sequence opens up additional genomic regions for targeting
- Shorter, 40-44 base guide RNA
- Two nuclear localization signals for improved transport to the nucleus
- 5’ overhanging termini on cleavage products
- Active from 16 to 48°C
- Maintains activity at lower temperatures than the Acidaminococcus orthologs, permitting editing in ectothermic organisms such as zebra fish and xenopus
- High concentration liquid format can be used for microinjection, electroporation and lipofection.
