Single Stage Purification of CRISPR/Cas13a Nuclease via Metal-Chelating Chromatography Following Heterologous Expression with the Preservation of Collateral Ribonuclease Activity

Single Stage Purification of CRISPR/Cas13a Nuclease via Metal-Chelating Chromatography Following... CRISPR/Cas13a nucleases are currently considered to be the basis for the development of a new generation of biosensors for the ultrasensitive, in-field detection of bacterial and viral pathogens. A recombinant Cas13a nuclease with functional affinity was obtained as a result of heterologous expression in E. coli with a single-step purification process via metal-chelating chromatography with the N-terminal polyhistidine tag.

Abstract

CRISPR/Cas13a nucleases are currently considered to be the basis for the development of a new generation of biosensors for the ultrasensitive, in-field detection of bacterial and viral pathogens. A recombinant Cas13a nuclease with functional affinity was obtained as a result of heterologous expression in E. coli with a single-step purification process via metal-chelating chromatography with the N-terminal polyhistidine tag. The simplified procedure of Cas13a nuclease purification broadens the possibilities for the development and practical application of diagnostic biosensing systems based on it. Moreover, our results indicate that the currently uncharacterized protein U2PWF1 of Leptotrichia wadei represents Cas13a nuclease.
