Product Overview:
Cas12a, also recognized as Cpf1, stands out as a potent type II V CRISPR effector protein. Functioning as an RNA-guided endonuclease, it selectively binds to specific target DNA sites, executing precise cleavage under the guidance of single-stranded guide RNA. This versatile protein has found extensive application in the realm of gene editing, spanning microorganisms, plants, and animals, showcasing promising potential in the field of molecular diagnostics.
Cas12a's proficiency extends beyond its ability to recognize and cleave double-stranded DNA targets; it exhibits activated efficiency in cleaving arbitrary sequence single-stranded DNA (ssDNA). The strategic design of probes, adorned with fluorescence or other small molecule markers at both ends, facilitates signal amplification in DNA detection through CRISPR/Cas12a. Commonly employed detection methods involve real-time fluorescence and colloidal gold assays.
Noteworthy is the gRNA-specific recognition of the target region, rendering the CRISPR/Cas12a system a valuable "secondary screening" tool for scrutinizing DNA or DNA amplification products. This attribute contributes to the system's high specificity in molecular applications.
