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.
