Capping Reagent A – Acetic Anyhdride in Acetonitrile (75:25 v/v)

Description

Capping Reagent A

Acetic Anhydride in Acetonitrile (75:25 v/v)

Capping reagent A is a 25% (v/v) acetic anhydride solution in acetonitrile, used during the capping step in solid-phase oligonucleotide synthesis. It serves to acetylate unreacted 5′-hydroxyl termini, preventing incorporation of deletion sequences in the final product.

• Composition: Acetic anhydride in acetonitrile (v/v 75:25)
• Application: Capping reagent A for DNA/RNA synthesis
• Function: Acetylation of unreacted 5’-OH groups
• Instrument Compatibility: Manual and automated synthesizers
• Format: Ready-to-use
