Product overview


LwaCas13a (previously known as C2c2) is a crRNA-mediated RNA endonuclease derived from the Leptotrichia wadei strain. LwaCas13a specifically bands and cleaves the ssRNA target under the guidance of crRNA with a low dependency on the PFS site. In addition, when the LwaCas13a binds crRNA and target RNA to form a ternary complex, the trans-cleavage activity of Cas13a will be released to non-specifically cleave ssRNA sequences in the reaction system.

This product is a lyophilized glycerol-free LwaCas13a nuclease, which can be shipped and stored at room temperature. After being dissolved with its reconstitution buffer, it shows the same performance as the non-lyophilized type of LwaCas13a (C2c2) Nuclease (#32117, ToloBio). This product can be provided in a variety of lyophilized forms such as powder and beads to meet the needs of different downstream applications.




This product is stored and shipped at room temperature. After reconstitution, the liquid enzyme can be stable for a month stored at -20°C or below and repeated freezing and thawing should be avoided.
