Chemically modified guide RNAs for genome editing with Cas12b was written by Rajeev, Kallanthottathil G.; Chadwick, Alexandra; Reiss, Caroline. And the patent was published on October 14,2021.Application In Synthesis of (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol The following contents are mentioned in the patent:
Provided herein are compositions related to Cas12b guide RNAs. Also provided herein are methods for modifying target polynucleotide sequences and methods of treating or preventing a condition in a subject in need thereof, such as conditions resultant from the expression of ANGPTL3 or mutations thereto. This study involved multiple reactions and reactants, such as (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4Application In Synthesis of (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol).
(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4) belongs to tetrahydrofuran derivatives. THF (Tetrahydrofuran) is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries. Commercial tetrahydrofuran contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although tetrahydrofuran is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.Application In Synthesis of (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol
