产品概述

Description

GenCRISPR™ LbuCas13a Nuclease is an RNA-guided RNA endonuclease from Leptotrichia buccalis. Cas13a (previously known as C2c2) belongs to the Class 2 Type VI CRISPR-Cas system and contains a single protein effector with two HEPN domains. Cas13a exhibits two distinct ribonuclease activities. Cas13a possesses sequence-specific RNA cleavage activity in vitro and in vivo. And after specific cleavage, Cas13a activates collateral cleavage activity towards adjacent non-specific ssRNA sequences. The two distinct ribonuclease activities of Cas13a enable guide-RNA processing and RNA detection. The RNA detection empowered with Cas13a-crRNA complex and quenched fluorescent ssRNA as reporter has been reported to be versatile, rapid and high-specific.
