Intended use
This CRISPR Cas13a nuclease kit is suitable for the development of detection products based on CRISPR platform.
Detection principle
CRISPR Cas13a nuclease is a class II and type VI CRISPR system effector proteins with two higher eukaryotes and prokaryotes nucleotide-binding (HEPN) domains. It is a novel CRISPR protease that can be used for targeted RNA cleavage. While Cas13 protein recognizes and cleaves target RNA under the guidance of guide RNA, its collateral cleavage activity is activated, which can efficiently cleave non-specific single-stranded RNA (ssRNA). CRISPR/Cas13 can be used to detect RNA templates and amplify signals by designing RNA probes labeled with fluorescent groups or other markers at both ends. Common detection methods include real-time fluorescence and colloidal gold chromatography. At present,this system has been widely used in gene editing of micro organisms, plants and animals, and has great practical application value in molecular diagnosis.
Applicable instrumentYou can use microplate Reader, like BioTek Synergy etal. fluorescence quantitative PCR instruments with FAM channel if you use fluorescence method.
Operation procedure
1. Preparation of reactive substrates containingT7 promoter.
The reaction substrate could be nucleic acid amplification products of LAMP / PCR /RPA.
T7 promoter, 5’-TAATACGACTCACTATAGGG- 3’,should be added to the primer.
