Order *Guaranteed Predesigned CRISPR gRNAs

  • Synthetic SygRNA® gRNAs available in two-part (crRNA:tracrRNA) or one-part sgRNA formats. 
  • Perfect for animal model generation and cell model engineering.
  • Recommended to complex with Cas9 protein.
  • Lentivirus gRNAs are available as ready-to-use lentivirus transduction particles. 
  • Perfect for difficult-to-transfect or primary cells.
  • Plasmid DNA transfection-grade plasmid gRNAs available in a variety of vectors.
  • Perfect for transfection, nucleofection, and lentiviral packaging (Note: lentiviral packaging can only be achieved by selecting a lentiviral vector).
  • In Vitro Transcribed RNA  is provided in DNase-, RNase-, and protease-free molecular-grade water.

*We guarantee the performance of all predesigned Mission™ SygRNA® CRISPR. If your Mission™ predesigned synthetic guide RNAs do not yield detectable cleavage at the intended target site, we will provide you a one-time replacement, free of charge.
To qualify for this guarantee, please send an image or sequencing data from a single experiment demonstrating detectable cleavage using one of our available positive controls, side-by-side with the negative results from your predesigned Mission™ SygRNA® CRISPR. To receive your replacement, simply email CRISPR@sial.com and include sample data from a representative experiment (T7E1, TIDE, or NGS), specifying the Mission™ gRNA ID used.

Cas9 Products

  • Proteins — Choose from the largest portfolio of Cas9 proteins available for any application.
  • Plasmid DNA — Cas9 expression plasmids utilize the CMV promoter for effective, transient expression. Available with and without fluorophore and antibiotic selection elements.
  • Lentivirus — Select Cas9-expressing lentivirus transduction particles, with blasticidin or neomycin resistance.
  • CRISPR Activators — Synergistic activation mediators (SAM) are potent transcriptional activation protein complexes. Our SAM CRISPRa system uses CRISPR-Cas9-mediated guidance to target SAM components to gene promoters, enabling site-specific transcriptional activation of a gene of interest.
