What is the difference between A.s. and L.b. Cas12a? When should I use one or the other?

A.s. Cas12a is from Acidaminococcus sp. BV3L6, and L.b. Cas12a is from Lachnospiraceae bacterium. Both utilize the same TTTV PAM site and crRNA design considerations.

Both Cas12a nucleases result in robust editing at target sites at 37°C, with L.b. Cas12a also resulting in high editing efficiencies in plant genomes and at lower temperatures, such as 23°C.
