Storage and Handling

• Storage: Store at −20°C in a dry, tightly sealed container under an inert atmosphere when possible, unless otherwise specified. Protect from moisture, excessive heat, and prolonged light exposure.
• Handling: Handle under anhydrous conditions to preserve phosphoramidite reactivity. Prepare solutions using dry, compatible solvents, such as anhydrous acetonitrile, when appropriate. Minimize atmospheric moisture exposure and prepare fresh solutions for oligonucleotide synthesis. Use validated coupling and deprotection conditions that preserve the N6-methyladenine modification.
