EasyGuide CRISPR platform for in vivo cloning of gRNAs and Donor DNAs
EasyGuide CRISPR Suite:
-
A modular and versatile platform for genome editing and synthetic biology in E. coli and S. cerevisiae.
-
In vivo cloning of gRNAs — Seamless assembly of single or multiple guide RNAs directly in E. coli and S. cerevisiae using the pEasyG1–G4 plasmid series.
-
Multiplex genome editing — Simultaneous targeting of multiple loci for rapid construction of complex genotypes.
-
EasyAssembler — A companion system for multipart DNA assembly, enabling combinatorial donor engineering and pathway construction.
-
EasyOligo method — Uses PCR amplification of oligonucleotides to generate gRNA and donor cassettes, eliminating traditional cloning steps.
-
Genome-wide programmable regulation — In vivo cloning of large gRNA libraries to drive CRISPR interference (CRISPRi), activation (CRISPRa), and cytidine deaminase base editing across the genome.
