Cat: CAS13A


LwaCas13a Nuclease (C2c2) is a crRNA mediated RNA endonuclease derived from Leptotrichia wadei strain. In the presence of PFS sequences in the target single stranded RNA, it can specifically recognize and cleave the target RNA. In addition, Cas13a also has trans cleavage activity (i.e., bypass cleavage activity/accessory cleavage activity), which means that when LwaCas13a protein binds to crRNA and target RNA to form a ternary complex, it is activated for trans cleavage activity against non-specific sequence single stranded RNA, shredding any sequence single stranded RNA in the system. This activity has also been used in the development of rapid detection kits for target nucleic acids.
