Synthego CRISPRevolution Chemically Modified Synthetic sgRNAs

Synthego has announced new chemically modified synthetic single guide RNAs for CRISPR genome editing. The modified guides provide protection against intracellular immune responses in primary and stem cells and against exonuclease attack in both eukaryotic and prokaryotic cells. The sgRNAs are synthesized with 2'-O-methyl analogs and 3' phosphorothioate internucleotide linkages in the first three nucleotides at both the 5' and 3' end of the RNA molecule.
